I have a small collection of old cameras as well, but need more information about my most recent purchase of a Brownie Chiquita Holiday camera made in Mexico in 1957-62. It was discontinued in 1962, and I wonder if you know where I can get film, (127) these days just to be sure it works?

It's been nice chatting with you. Do your cameras work? How about a picture?
