Griffon Spitfire Radiators

[Ed Russell]

Would anyone care to comment on Griffon Spitfire radiators as mentioned in this post.

Were all Griffon engined ones the same? (Edit - probably not!)

Was the 22 and 24 shape the same as the PR.XIX? Looking at the Mark 1 Guide, I would say not and that the PR.XIX shape can't be extrapolated to the 22/24.

Does anyone have a full underside shot of a 22 or 24 radiator?

I could give you a photo walkround of the MK19 ones if needed

The frontal area of the XIX radiator differed (very) marginally from that of the 22/24, and the Morris part nos differed, as well; coupled with the different wing, introduced on the 21, there's a distinct possibility of a mismatch, albeit slight.

I think what I am asking is -

Is the flat bottomed and square sided PR.XIX radiator assembly (radiator block plus external fairing) seen here

the same as the apparently more round bottomed (albeit practically flat sided) Mk 22/24 radiator assembly seen here

Are there actual differences or is it an optical illusion that they are different?

Hiya Ed - I must admit that I think the shape of the Mk XIV / XVIII radiator and that of the MK 21-24 rads is different in profile.

Building a MK XVIII at the moment and I've been loomking at the Aerocblub mk 21 rads, and they are different shapes.

I would say the MK 21 shape has a curved bottom and is perhaps shorter too, while the XIV/ XVIII has that flat bottom section your pics show, and I think they are a little longer too.

It will be Interesting to see where this goes, as I'm just at the radiator stage in the build!!

The oil cooler is the left one, the right is the rad and intercooler on the 19 I believe, one behind the other, on that picture you have 2 coolers side by side as in a merlin spit.....

Hi,

I just posted some of my Mk XIX radiator pix from the Swedish AF Museum on:

http://www.britmodeller.com/forums/index.p...=54540&st=0

Hope they can be of some help.

I have to admit that I haven't had close up access to a Mk 21 or 22, so I'm prepared to hide my head in shame should it transpire that those rads are, in fact, curved in plan view. ;-)

Best,

Joachim

Hurry up and commit yourself on this step, Jon, then we'll get fantastic detail showing your choice to be wrong!

I have always assumed that the 21 series radiator cowling (to use a term that Supermarine seems to have used) was different from that of the XIV/XIX/18, but I don't have any documentary evidence to hand...

Interestingly, the radiator core part numbers, for the 22 & 24, are identical to those of the Seafire 45-47, and those photos, of the side of the 24's radiator, seem to show a very similar forward (backward?) rake to the rear of the housing, just like the housing on the 47.

I'm hoping to visit a mk 24 on Saturday. Assuming I can, I'll get pics.

Cool and welcome to the forums James

Thanks Tony. Well, here they are - though from some angles and photos they can look flat, they are definitely smoothly curved on all three sides. I've posted a few here, but assume you can browse my Photobucket account (http://i1045.photobucket.com/albums/b452/PaveShadow/) where I've posted other angles etc

Further googling comes up with this interesting image, suggesting that 21-24 does not equal 19 => http://www.rcmf.co.uk/gallery/albums/userpics/11590/PIC8.jpg (for the scientists among you, this is the exception thereby proving the rule)

That's one image, but there are some other useful ones as late mark reference photos on the same page +. http://www.rcmf.co.uk/4um/index.php?cat=336%3Btpstart=10 (also note in the pic the early Mk.21 type tail, - a look through the records will probably date this in a very short (e.g. 2 weeks) between exit from prod, to dissappearing into a maintenance unit for a few months, and then getting a Spiteful tail)

P.S. - Would welcome feedback on above post - or are you looking for a different angle? If so please let me know.

P.P.S. - also note that photo 4/6 above shows some customisation by the pilot. This should NOT be taken as a full reference for your models - he had to land wheels up to achieve this buckled flap effect.

Feedback - Thanks for the pics and the link - very helpful.

My conclusion is that the kit supplied 22/24 radiators are correct, with the proviso the Jays is a little tiny bit too narrow, easily fixed.
