re: the rear aperatures aesthetics... if you have some closeups or know where to find them post them up... my brother restores cars and builds hot-rods/racers... I suspect we could poweder-coat at least some of the surfaces to match the bluing on the No. 1s... the other would be to find someone to annodize them black... need to be careful of the precision parts though, but again, I think it can be done...

I just like the ghost ring fronts (I think that's the right term... big circle with a post in the middle?)
