Just purchased this Maynardcartridge in a deal involving numerous other items for my modest collection. It is WAY outside my field, which makes it an interesting addition. Two questions:
There is no headstamp or other markings. It does not have a “rivet” in the head, unlike the other example I found in this forum. Who is the likely manufacturer?
How do I classify this cartridge? (Obviously it is not a centerfire in the modern sense.) It has no exposed primer, and I am unfamiliar with this type of cartridge. Barnes’s catalog, COTW, describes it only as “externally ignited.”
