Nice job, good find! Way back in the day, I talked my way into the Numrich warehouse, they had bins and bins of M1parts stacked five high. I pulled down a bin of sights and examined a couple of hundred... the bottom of the bin was covered with sight seals that had either fallen out of sights or just tossed in there. I took three or four
When I went back to the shop for them to price the parts, they had no idea what to charge, so the guy said, "Ah, just take them, no charge."
