My Father in law has an press camera, Speed or Crown Graphic, I was tinkering with it this evening but cannot remember now off hand which. I was wondering if there was a site that I could go to to compare serial numbers to try to figure out when it was produced. It has a 2 1/4 x 3 1/4 back on it, and it had I believe a 101mm Ektar lens. It looks as if it just came out of the box from the factory. I cannot wait to take it out to play. Any direction would be great, I am just venturing into medium format with my "new" autocord and am looking forward to tinkering with this great camera as well.
