I removed the screw that holds the bolt stop in the breech but it wouldn’t come out.
So I repeatedly flicked the bolt under its spring’s power and it came out.
The bolt seems to hang up on the rather sharp transition between the main diameter and the probe, so that will need to be addressed.
Removed one pin…
Trigger and transfer bar (?) units.
I removed the stop screw.
And rotated and pulled off the cutoff for the cocking lever.
It’s a neat part.
It was spring loaded.
I was going to remove the front catch pin for the cocking lever as it also holds the front breech cap in place but…
Looks to have been peened in at the factory, so best to just leave it be.
And last, the spring, compared with one from an IZh-61. The broken spring had 3 or so less coils and was .118 vs .100 diameter wire and was smaller in both inside and outside diameter. I think it may have been an attempt to get more power by a previous owner as I would assume it would have the same spring as the IZh-61. But who knows.
Now to clean, lube, repair and replace items and get it up and running. Then figure out what sort of sights to put on it.
