Hi,
I'm wondering if anyone could add any information on this shutter/lens combination beyond what I've been able to find out so far. I picked this up several years ago at an antique shop for around $7, and now that I have some LF cameras, have begun experimenting with it.
What I do know is that it's manufactured by Rochester Optical & Company/ Bausch & Lomb Optical Company, which eventually was bought by Kodak I believe. Speeds are T, B, 100, 25, 5, 2, 1. F-stops are 6.3-45. Only T, B, and 1/100 work at the moment. This shutter fits a Copal 0 lens board. There is a single rear lens element. At first I thought it was missing the front element, but now I don't think it is. I have a 4x5 camera with long enough bellows to focus it, and I'm able to get a clear image. I suspect that it's around 300mm focal length, and will certainly cover 5x7, and possibly 8x10, but I don't have a camera that big to test it. I suspect that it's from around 1900, due to the manufacturer, and that it has a pneumatic shutter release. Thank you for any additional info you can add.
