My high school shooting buddy found and scanned his Arvo Ojala and Andy Anderson catalogs from about 1969. For years, my memory has been that he bought an Anderson holster, but he now tells me it's an Ojala. Some of this is on the Internet, but these are slightly better quality than I've found. Plus some ads.
