Hi

I just got a Zeiss Tessar 250 mm f4.5 Globica. I didn't receive the lens for now but I'm looking for diameter of a retaining ring and the size of the hole I need to bore in the lens holder. The retaining ring is not included with the lens. It is a barrel lens.

Do you know the answer or where to find them?

Thank you
