I bought a real camera earlier this month. It was expensive, it's cobbled together with parts from broken cameras, I assume, as nothing really matches. The roll film back is home made, but is clearly useable, and the shutter works
Reality is the brass parts are worth what I paid, and the lens is a nice little Emil Busch Bis-Telar.
Bargain of the same day was a set of Half plate bellow for 50.
I've patch 2 corners internally, and then restored the bellows, fixing a few pinholes. Just need to decide which camera to fit them to,
Also I bought 50 sheets of 5x4 film for £10, and a cheap broken Exacta Varex,IIA for it's 135mm f4 CZJ Sonar lens, Lens is toast camera body works fine,
