I have had four of these and done some restoration. New seals and parts also available from http://www.theschimel.com/ The photo with two pistols in a case on this site were mine. One problem that I found which is not easily noticed are tiny scatches in the gas chamber where people have removed old seals with metal tools. Only plastic and wood implements should be used for this job. The scatches will cause leaks and need to be polished out.

Best regards, Baz
