That`s gonna make it longer to ID but we`ll get it. I`m trying to see how the throw mechanism works but there`s so much coard in the way. Does it tighten ? It looks like just a lift screw and not an actual throw off with a lever. That`s how they all were back then and it may push this back to teens or single digits.
No throw whatsoever.
There's the screw that you see that tightens straight to the butt plate, which does not attach anywhere. The butt plate simply sits above the ring of the bottom head and is held in by tension alone.
