Thanks, guys!
I got the bug for the 60's rebuild marked Garands and glommed a USMC rebuild last month. Those have the "O-6x" mark on the upper receiver, which shows up in the pictures.
I figured that I would have trouble getting a LEAD, RRAD, or TE rebuild at auction, because auction houses usually do not break rifles down for their online auction pictures.
I was shocked while perusing the auctions to find the listing with the "LEAD 3-65" displayed in the pictures.
