Harrier/ViperFan Posted December 20, 2018 Share Posted December 20, 2018 I have a really noob question, I have a Tamiya 1/48 P-47D Razorback that I might start over the Christmas period, the scheme I have chosen calls for the Hamilton Prop but I can not tell which one out of the 2 supplied is the one I need. Can someone please help me by pointing me in the right direction. Link to comment Share on other sites More sharing options...
Army_Air_Force Posted December 20, 2018 Share Posted December 20, 2018 Hamilton Prop... Curtiss Prop... Link to comment Share on other sites More sharing options...
Chuck1945 Posted December 20, 2018 Share Posted December 20, 2018 I have the 1/72 kits, not 1/48 so can’t give you part numbers. On the sprue, the Curtiss prop has a pointier spinner and the H-S prop spinner is bigger and more rounded. The H-S prop blades are wider along the entire length too, thinking if it is the Razorback kit, the Curtiss blades are the narrower, pointy tipped ones, not the paddle blade version Link to comment Share on other sites More sharing options...
72modeler Posted December 20, 2018 Share Posted December 20, 2018 (edited) AAF, Yep. There were actually four props possible for P-47's. The original "toothpick" Curtiss Electric narrow chord prop, the CE paddle blade prop with asymmetrical blades, as seen in the post, a CE paddle blade prop with symmetrical blades (late production and P-47N) and the HS paddle blade prop, as shown in the post. I have attached a link to photos, drawings, and text that show the different props; I think it would be useful for anybody building a P-47. Mike http://p47.kitmaker.net/modules.php?op=modload&name=SquawkBox&file=index&req=viewtopic&topic_id=128328 H/VF, I have the 1/48 Tamiya razorback kit. P/N 36-37 is the HS prop; 32-33 is the CE narrow chord prop; 34-35 is the CE symmetrical paddle blade prop. I would suggest you use a photo of the one you want to build for the prop type fitted, as it was very common on P-47's to have the prop type swapped for a later, more efficient type by an enterprising crew chief or during overhaul or engine replacement. If you look at photos of the war-weary P-47D razorbacks used by the 5th ERS, you will see Jugs with all four types fitted! (If the airplane you want to build had the CE asymmetrical paddle blade prop, you will have to get it from one of the aftermarket sources, like Ultracast or Barracuda.

BS_w Posted December 20, 2018 Share Posted December 20, 2018 symmetrical paddle blade, cuffed = CE 836, uncuffed = HS 6507 asymetrical paddle blade = SPA blades on CE hub all other blades are narrow blades(CE 714, 2721200....) Curtiss & SPA(AO Smith) blades: http://lapatrouillesimple.forumgratuit.org/t582-les-helices-curtiss-electric 2 Link to comment Share on other sites More sharing options...
Harrier/ViperFan Posted December 21, 2018 Author Share Posted December 21, 2018 Thanks Guys some really great info there. Thanks for pointing me in the right direction. The plane I am building is: P-47D-4-RA, 48-22762 Lt Samuel Stamps of 56FG/63FS, Halesworth Feb-March 1944 I am not sure now if it's a Hamilton prop.

72modeler Posted December 21, 2018 Share Posted December 21, 2018 H/VF, Are you sure about the serial number? I don't think that can be right, as in the AJ Press and MBI monographs, the serial number range for the P-47D-4RA was 42-22664-22863. The last P-47 built was a P-47N-20RA with serial 45-50123. According to the same sources, the prop, as originally fitted, was the narrow chord Curtiss Electric, but if you have a photo, I would go by that, as different prop types were oftentimes fitted, as described above. In the Little Friends website, his P-47 is listed as 42-22762, which would make it a D-4, and it was coded UN-S; the airplane was later transferred to the 366th FG, 9th AF. I couldn't find any photos of his Jug, however, sorry! I have posted the link to the website, as it is an outstanding modelers reference for all of the 8th AF fighter groups, with tons of excellent photos.

72modeler Posted December 21, 2018 Share Posted December 21, 2018 BS_w, I meant to thank you for your post- first time I have seen specs and markings references for the prop blades made by AO Smith, who also made prop blades for P-61's, IIRC. Merci! (That's French for much obliged, podnuh!) Mike Link to comment Share on other sites More sharing options...
BS_w Posted December 21, 2018 Share Posted December 21, 2018 thank's Mike it's correct, P61C propellers were fitted with SPA 9-200 blades,(Also SB2C-5) Link to comment Share on other sites More sharing options...
Harrier/ViperFan Posted December 23, 2018 Author Share Posted December 23, 2018 my mistake it is 42- I mistyped, so I go with the Curtis prop for my choice? Link to comment Share on other sites More sharing options...

BS_w Posted December 23, 2018 Share Posted December 23, 2018 (edited) the hub is not enough massive to be HS propeller. It's probably a Curtiss prop with narrow blades, drawing 714 or 2721200. Pn this pic the nose is yellow, not red as written in IWM Edited December 23, 2018 by BS_w Link to comment Share on other sites More sharing options...

It's definitely a CE hub, and most likely, based on the markings visible, that it had the early narrow-chord prop blades. Neat photo, though!

Seahawk Posted December 23, 2018 Share Posted December 23, 2018 If 42-22762 was a P-47D-4, wouldn't that predate introduction of the ability to carry a belly drop tank and mean a shallower keel under the fuselage? Which will worry you as much as you let it. Link to comment Share on other sites More sharing options...

Which will worry you as much as you let it. Have to go back to my references, but IIRC, there were factory kits supplied to early production blocks to fit the rack and plumbing for a fuselage tank/store, just as there were kits supplied to add underwing pylons/plumbing for the same to P-47's that did not have them installed on the assembly line. The "big belly" keel was also a factory supplied modification kit, if memory serves. Mike Link to comment Share on other sites More sharing options...
greatgonzo Posted December 24, 2018 Share Posted December 24, 2018 That's right. A bit 'lego-like' construction of P-47 made it possible to see D-2s indistinguishable form late Razorback models. The nose colour is Sky type S - a short lived markings of 63FS. This dates the plane to Feb. 1944. The screw is CE of course, and it can be seen clearly on better framed copy of the pic. What kind of prop blades is a different story. At the time replacement paddleblade screws were used by 56th FG but some craft still flew with original 'toothpicks'. It is to decide how important Lt. Stamps could have been in the squadron those days ;). Link to comment Share on other sites More sharing options...

Wonder what strings the 5th ERS crew chiefs pulled, as many of their war-weary Jugs had the later paddle blade props and I'm willing to bet the uprated P&W R-2800's, too. Some had six or four guns, so betting they were "hot rods" if they got both the HP props and engines! See the link below for a photo of one of their Jugs with the asymmetrical paddle blade props and only 4 .50cal guns.

greatgonzo Posted December 25, 2018 Share Posted December 25, 2018 There was no need to pull any string really. 5th ERS flew its first mission in the middle of may 1944. Most of the known pics of the unit's Thunderbolts are post D-Day. This was the time when paddleblade screws were widely available and that's why pictures of 5th P-47s with toothpick are so rare. For me the surprise is the planes retained their Malcolm canopies. It seems quiet different to the policy connected with P-51s. Link to comment Share on other sites More sharing options...

Perhaps they rated the Malcolm hoods for their better visibility during SAR sorties? Merry Christmas, GG. Mike Link to comment Share on other sites More sharing options...
