Here are some photos of a FED-Zorki that I have bought on Ebay recently (but not received yet ... so, the seller's photos). Maybe some of you have seen it or bid on it also.
This camera comes with a 1947 ZK 50mm F2.0 Rigid lens ...
serial number 000047.
As you can see from the photos, the camera itself is FED-Zorki 1948, No. 04285. So possibly this is not the original lens for the camera.
But, if not for this camera, what camera would this lens have been made for? And, is this the earliest ZK 50mm lens that has been seen? Is it the 47th ZK lens made?
Please give me some opinions or theories, if you have them!
