Hello, I'm new over here and mostly a newbuck to Maxims. Eager to learn and identify Maxim lock parts for which model made by who and what works with 1910 Russian locks. I have annotated the pictures to what I think is correct but could be wrong. I've read there is some interchangeability. I have the Devil's Paint brush and it only helps go so far. I'll post the pictures shortly when I figure out how.
