barrel question

[Autumn Daze]

The actuating end of the bolt is the same on hammerless guns. It has more to do with having the correct mating angles.

I have to admit I have heard this question asked dozens of times over the years and I still don't know the answer. Which bolts are compatible with which lug slots? Obviously the straight bolt is not compatible with the angled 1910 lug slot, but what about the first generation straight soldered in bolt plate? Is the straight bolt compatible with that slot? It is clear that no one who has posted so far knows the complete answer. Maybe Lawrence DelGrego will give us the answer.
