Thanks CJ,

These are great suggestions... I have an adapter board that came with the camera... It is a vintage thing made to accommodate lenses that are a little larger. The camera came with a 14" Zeiss Anastigmat in a B&L Iris Diaphragm shutter. A betas #5 may fit on that... I will check. A brass landscape lens separated from the diaphragm was what I had been trying to find. I have a a couple of front mounted packard shutters in large and small sizes so shuttering a lens is not a problem. I am so fond of this camera that all the trouble to find the lens seems worth it! Thanks again

Best... Chris
