Question about lockwork on early HE models

[handejector]

When did it start, what guns was it done on, and when was it discontinued, and what did the factory call this feature and name the parts?

That is a "yoke stop". Keeps the cylinder from flopping around. Did you find 'em?

They were on all frame sizes.
N- Triple Locks thru the 357 Mags. Later 1917's did not have them.
K- Early till the late 20's, maybe early 30's
I- Early till ?? I don't know for sure, but I have seen them into 1903 variants.

Gotta go- I need to stick some rebound slides together and try to pull them apart.

Ha - very funny!

Actually, I didn't loose them - I was lucky and was working carefully over a towel. They just plopped out right in front of me - no drama or running around looking for parts (entirely unlike my first time disassembling a sight assembly)!
