Many of you may be aware of the ATFE website. If not, there is a fairly complete gallery showing a large number of indexed headstamp images found at afte.org/ExamResources/galle … p-Gallery/ In some cases there is a narrative about the cartridge manufacturer provided. In others, very little information (if any) is given.
Exploring this site reveals that just because a HS does not show up alphabetically, numerically, etc., does not mean it is not present somewhere in the database. I also discovered that searches on one HS can turn up unrelated headstamps. I don’t know how that can happen, but it does. Playing around with search features does help to figure out the eccentricities of the AFTE database.
