It was broken off at some point for sure ... by who, we will never know.
One thing for sure is who ever tried to repair it wasn't a qualified gunsmith (god i hope not)
Here's a few more pictures.
The first is of the rifle when i got it ... at first glance it looks rater nice.

Next one... the collar doesn't even touch the back of the cut bolt head. It is fully inserted.

You can see holes in the welds making the integrity of the repair rater sketchy to say the least. The repair is also crooked.

No idea what happened at the back but someone seems to have thought hitting it would help things.

And last but not least the repaired tip being too thick for the hole he decided to enlarge the hole.... yet like i mentioned and showed above it is still too small.
Guessing by then he just gave up on ''fixing'' it.
