This recently came into my possession with some other materials. It appears to be a 320 with Type I perforations. The hole size and spacing matches the template on the Precision U.S. Specialty Multi-Gauge exactly. From Scott's Specialty Catalog I understand many of the private perfs are faked. I am aware of different publications available on private perfs from a search of this site, I don't really collect these so I am looking for opinions whether people think it is real or fake and why. Thanks for any help.
I also compared the perfs to some other examples know good examples because the top perfs looked somewhat odd. This didn't help me since it showed there is variability.
