Yep, loads of them were finished in dark wood. A lot of the last wood and parts used by Fazakerley came from the 'close-downs'. The 'close-downs' were the factories and small concerns that were making the stuff that were closed down. All of the material that was produced was paid for and taken away for stock and the contract cancelled. Stuff that was contracted for but unfinished wasn't paid for but they were allowed to keep (from Sten gun research) to help them back into post war production. So for example, a company making radio chassis/bases that had turned over to making Sten magazine casings or, say, No4 upper bands could keep the steel that that already had to aid their return into commercial production of whatever. There was a LOT of post war barter too.

I have a couple of dark/walnut No4 fore-ends from F55 production.

But to be honest - and frank too - , we didn't give a toss what colour it was just so long as it was a reasonable match
