My Dad had one also, it was his first rangefinder camera after trying to use an old clapped out bakelite camera that someone must have given him. He took lots of family photos with the Neoca during the 1950s. In his latter years he gave me all the negatives which I still have, stored safely. He developed them himself and they look pretty good.
Unfortunately Dad's Neoca was stolen, so, for nostalgia, I bought one as part of my collection, and also as a bit of family memorabilia.
