Want to Buy Small Packard shutter 5 or 6 with a 3 1/2 to 4 inch square frame.

Looking for a small Packard shutter 5 or 6 with a 1 1/2 to 1 3/4 inch opening and a 3 1/2 inch to 4 inch square frame. Probably a long shot but if you have one lying around I could find it a good home. I have lots of brass LF lenses and maybe I have something you want or a straight sale is fine.
