These bands can be found marked on the right side UI, often times with the I stamped very lightly. Some are 2 weld others 3. Some marked, others not.
Band swivels can be found marked and not marked.

Stock looks to have been sanded heavily around the comb, grip and the bottom side.
Can you see how far the bottom of your trigger housing hangs down, under the stock?
Pictures showing the inside milling style of the stocks barrel channel can often give us a lead on who the original maker was.

Listed parts indicate it's a mixer, but then again 90% + are.

Is there any type of staking on top of the receivers dovetails visable that's holding the rear sight in place?
