Hi,
I was thinking that in 50 years time there will be home chip kits and a few people making them for fun. In the same way that there are people these days with proper workshops with lathes, milling machines etc, etc in garages.
If I wanted a part made for a Leica nowadays I might just find someone in the local model railway club who could turn out a dozen. In the same way that somewhere there's someone still making parts for old fashioned wind-up watches, even the ones with keys. And shooting muzzle loaders that take black powder only, and casting the shots etc. What it would cost doesn't bear thinking about but that's often the last thing people think about when driven to get something old restored or working.
Most of us on the forum are using elderly cameras for the hell of it; my pre-war stuff turns out excellent prints but life would be a lot easier with a film or digital P&S but just not so much fun.
Regards, David
