Different Mosin arsenal marks

[Robertroadking]

I have not been able to find info relating to the changes in Arsenal marks on small parts, such as small hammer and large hammer Tula , same with Sestroretsk arrows, I have parts with large and small arrows and I think there are differences in the bow and arrows as well?
Is there a time line to these changes?
And when did they discontinue the sling swivel on the trigger guard?
What about the cocking knobs, when did they go to the smaller knob without the relief cut?
Most sources I’ve found may say earlier versions, that doesn't tell much.
