Well, it seems that the ammo they had at Larry's in Huntsville turned out to be 7.65 Browning(AKA .32 auto), not 7.65 French Longue. Graf lists the brass, but it is out of stock. The bolt stop is about 80% finished and it looks like it is going to work with a little more tinkering. With no good pictures or drawings of the part, I'm having to figure it out as I go. The only pre-heat treated steel I have on hand is 4130 so I made it out of that. My only worry is how well it will hold up in use. The only part of it that has any real stress, besides the pin that the link attaches to, is the tab that locks the bolt open. I have no way to test the hardness of the steel. It sawed and filed alright, but took more pressure to cut than annealed steel. I guess if we can't find any ammo, it will last quite a while. The owner talked as though he might be willing to buy a die set, so maybe he will eventually get to shoot it.
