I'm in the process of building a complete system around a top mounted rangefinder Crown Graphic I won recently on Ebay. I also have a 90 mm and 300 mm lenses and I'm trying to find either a cam or a pattern of the cam for the 300 mm lens. I got lucky when I found someone on Ebay selling an identical 90 mm lens to mine with a cam and he was able to scan the cam and email it to me. I'm also looking for the wide angle optical mask adapter that would accomodate my 90 mm lens. According to my Graflex manual, the catalog number is #3060 and I believe that it probably has a supplementary lens built into it that provides a wider viewing field through the optical viewfinder.

Can't help you on the cam, but Midwest Photo Exchange (www.mpex.com) used to have a heap of 3060s. I don't enjoy looking for things on their site. If I were you, I'd you get the phone # from the site and then call.

Cheers,

Thanks for the lead, I'll check them out.
