I actually don’t have a picture of it right now because I’m at work for another two weeks. But it is a thin top strap model, it’s serial number is 4472, if I remember correctly. 44 something anyways. It hasn’t eroded into the top strap as these are rumoured to do. That was why they thickened up the top straps but they (Swiss Ordinance) never loaded these rounds with smokeless. It was about the world’s last blackpowder service cartridge, being a coal-burner right to the end (1960’s for Swiss Border personnel, I believe). It had gas-cutting issues with blackpowder, not just aftermarket smokeless rounds.
