The Kodak Retina Ia (Type 015) was built in a number from 137,000
pieces from 1951-54 in W.-Germany. The price was in W.-Germany 218 DM.
The lens is a Schneider Kreuznach Xenar 2.8/50mm and the shutter is a Synchro-Compur. See more pictures of the Retina here!
I used a since 12/2015 expired Kodak Color+ 200, which I've bought in Brazil, with the Retina.
