Yes, that photo was definitely an inspiration for me. The original is available from the Imperial War Museum web site.

 

I think the version you've posted has been colourised from the black and white original. Whoever did it looks like they coloured the collector ring Based on false information. Wink

Well, it depends on the reference sources, but I've seen bronze as a colour call-out for collector rings before.

It used to be the go-to colour in most kits back in the day. The Airfix call out is now Humbrol 53, which I think is gunmetal, which seems much more appropriate.

Yes another lovely rendition of the Blenheim Heather and I do like your display pictures of your finished models, far better than my efforts. 

 

But in relation to the collector ring colours I was given to understand the collector rings were stainless steel so the Gun Metal 53 colour given by Airfix's colour call-out may be  near correct when new, but heat tainted the rings a bronze tone which is the colour Airfix stated in most of their older tool kits with similar collector rings?

Well, yes, collector rings can heat stain; there's also some suggestion that some of them may have been painted ex-factory, and the metal colour is only revealed when the paint chips and/or peals and/or burns off.

As to "what colour does stainless steel start as?" and "what does it discolour to?" that's opening another can of worms because it will depend on the grade of stainless used!

which has a couple of pics of the last flying Blenheim. It's a stainless steel ring but engine heat has turned it a copperish colour. A K interactive do metallic waxes. Their copper lightly applied over gloss black worked for me on a Beaufighter.

Excellent posting! That Blenhein picture really does it. The old usage of bright Bronze/Copper needs to be put down. This diagram points out how the collector heat stained.

Thanks for the comments, and for the collector ring colour debate. All useful stuff. =o)
