I recently acquired a Burke & James 5X7 which came with an old lens mounted behind an Acme #3 shutter. Actually, the shutter was taped to the front of the lens. With electrical tape!
I removed both since I planned on reconditioning the camera and using a newer lens. I got bored this evening and decided to see if the lens was actually supposed to be crusty and green. It wasn't.
Underneath was a beautiful brass barrel lens. It is a 240mm (marked 24 cm) Rodenstock Doppel-Anastigmat Eurynar f/6.3. The front section of the body says "G. Rodenstock, Munchen."
I'm sure it's pretty old but the glass is slightly dusty, no separation or fungus. Probably not coated. Perfectly clear though. The elements can all be removed and the glass cleaned up.
My question is - having recently acquired an old 5X7 Solar enlarger in excellent shape, I'll need a lens. The 240mm might be a bit long. Is there any reason this lens can't be used for enlarging 5X7?
I'd appreciate any input and information on this use as well as about the lens itself.
