I have an A1 stripped upper receiver that only has marks where the sight adjustment wheel has been installed on the right side and where it must have been attached to a lower. I bought it off of the EE about six months or so ago for a project but I am going in a different direction now.
It does not have any manufacturer marks on it and I don't recall what I was told that it was.
May consider M1 Garand parts in trade.
I will take Paypal but you pick up the 3% extra.
