What size/type of filters do I need for my Industar 22 f3.5?

I did do a search and did not find what I was looking for.

Thanks in advance.

Hello Mark, try Yuri at Fedka.com for a 36mm filter.

It should use the same screw-in filters as a Leica 5cm f3.5 Elmar. I think it is 19mm screw in. It is also the same as the Argus C-3. That is what I use, a Walz filter for the C-3, for my Elmar.
