It was my father's, he bought it in 1972.
The model is "Canonet QL17" or "G-III QL", I'm not sure.
It uses original "photographic films" (english is my second language so I'm not sure its the right term).
40mm 1:17 is written on the lens.
I'm trying to find what it is worth as I entend to sell it.
Any usefull information is welcome.
