Johnson Posted August 29, 2021 Share Posted August 29, 2021 Hi Folks, I'm building this 1940 JG 27 Bf 109E-4 using the 1/72 Airfix kit. The wheels look like they were painted either RLM70 Schwarzgrun or black, hard to say from this B&W photo. Any opinions on the correct colour? Many thanks, Link to comment Share on other sites More sharing options...
Hook Posted August 29, 2021 Share Posted August 29, 2021 Black was the colour stipulated by the authorities. Cheers, Andre 1 1 Link to comment Share on other sites More sharing options...

I emphasise the gloss bit as the reflections can make them look lighter.

72modeler Posted August 29, 2021 Share Posted August 29, 2021 The wheel hubs of many Luftwaffe aircraft were manufactured using a magnesium alloy which went by the trademark name of 'Elektron.' Being magnesium, they were painted with a semi-gloss black lacquer to prevent corrosion. BTW, the process of making the magnesium alloy was originally developed by a British company!

Mike There was a lot of cross-pollination between the British and German aviation industries between the wars. And they both used NACA reports from the US. Funny you mention corrosion and magnesium. Back in the 80s or 90s, the USAF was running short of mainwheels for its F-4 fleet. The magnesium elements of the wheels in use and in reserve were corroding and the wheels were becoming unserviceable. The service was looking for a vendor to manufacture more wheels, but in the meantime, instead of receiving a built-up wheel and tire at the tire shop when doing a change, the old tire was dismounted. The wheel was then inspected for serviceability, and if it was good, a new tire was mounted and balanced before reissue back to flightline maintenance. A 30-minute process became an hour or more.

fishplanebeer Posted August 29, 2021 Share Posted August 29, 2021 In 72nd scale I usually use satin black for the wheel hubs and RLM66 for the tyres and this seems to look OK. Regards Colin. 6 Link to comment Share on other sites More sharing options...
fishplanebeer Posted August 29, 2021 Share Posted August 29, 2021 What's interesting about this particular aircraft is that it is always shown with a yellow nose but with the camo colours retained on top which I've always thought of as rather odd. If the Germans applied the yellow noses to aid recognition it seems strange that they would then retain the camo as it would rather defeat the object of painting the nose yellow in the first place. In the photo the nose appears to be the same colour as the RLM65 fuselage just around the intake area so could it be that the actual nose wasn't yellow after all? Just a thought. Regards Colin. 1 Link to comment Share on other sites More sharing options...
fishplanebeer Posted August 29, 2021 Share Posted August 29, 2021 Sorry, the only reason I mention this is that for ages people thought the Von Werra machine had a white nose with the camo retained but it turned out the cowling was RLM65 after all so could this be another case of colour misinterpretation perhaps? Unfortunately I don't have access to the official crash report so this may be more definitive in terms of the actual colour of the nose.

John Masters Posted August 29, 2021 Share Posted August 29, 2021 I am always astounded at how grubby these aircraft became, especially it seems, the Gustavs. Such harsh conditions...different types of smoke, dust, snow, rain... It's a good reminder to make them grubby looking...more fun too, I suppose, unless they are factory fresh! Oh yes...I agree. Black.😄 1 Link to comment Share on other sites More sharing options...

Unfortunately I don't have access to the official crash report so this may be more definitive in terms of the actual colour of the nose. When I started the kit, with this plane in mind, I wondered the same, was the nose actually just RLM 65? But quite by chance, looking for other details about the crash, I came across this which, according to the source, is the actual crash report; Made me feel better about painting the nose yellow! It also mentions no head armour in the cockpit which is very useful. Cheers, 3 Link to comment Share on other sites More sharing options...
fishplanebeer Posted August 29, 2021 Share Posted August 29, 2021 Charlie, Thanks for that, so not another Von Werra oversight after all, though still puzzled as to why they did this as the camo just makes the nose less yellow and obvious which was sort of why they made them yellow in the first place, plus for me it just looks wrong. Every other pic I have of JG27 during this period shows either no yellow nose (early part of the Battle) or the nose completely yellow so this must have been a bit of a one off for them. Perhaps the pilot wasn't that keen on being too visible! Regards Colin. Ps. strange that not all Bf109E's at this time appeared to have part of the intake as blue but who knows why Link to comment Share on other sites More sharing options...
Peter Roberts Posted August 30, 2021 Share Posted August 30, 2021 Or was it just the lower nose cowling in yellow? Link to comment Share on other sites More sharing options...

I don't think that could possibly have been the case!!! Er... it's a good point. The crash report doesn't actually say which bit of the nose. Here are another couple of photos of the same plane taken in France. The first one, the lower section of the nose does look perceptibly darker and may be yellow. the second one has less difference. But what is evident is that there is little. if any, tonal difference between the side of the engine cowling and the side of the rest of the fuselage. But when did the Luftwaffe/RLM start painting the lower section of the nose yellow? Was it during the BoB? Cheers, 1 Link to comment Share on other sites More sharing options...

Thanks for the interesting story, BTW. Mike Mostly due to age, methinks, and wear on whatever protective coating had been applied to the magnesium at the time of manufacture. There were no new wheels in the supply system as the USAF was then engaged in phasing out the F-4 in favor of the F-16, and I don't think anyone had anticipated such an attrition rate that late in the aircraft's service life. There were similar shortages on the F-16 when I was in Korea in the mid-80s, but then it was because certain parts were failing unexpectedly and all such new parts were at the time going to the production line.

Cheers, I think I could be convinced that the cowl and fuselage are similar, but different tones of grey in this picture above. Look closely at the vertical panel line behind the air filter - could be two distinct greys - hence perhaps yellow cowl with camo on the top (sort of an early anti-glare panel? , with blue 65 painted on the panel behind?

fishplanebeer Posted August 30, 2021 Share Posted August 30, 2021 My only other observation now is that the line between the camo and the yellow on the nose is very precise and exactly matches the demarcation line before it, and the contour of the camo shows no sign of any minor variation or the slightest step so who ever applied the yellow must have had a very steady hand and been a stickler for detail. I must say that the idea that part of the nose was yellow (not specified in the crash report) would seem to make more sense on this basis but it's only my guess based upon the distinction of grey tonal values from the b&w photos and this is always very subjective.
