Yep, the very light gray park is indicative - though not with 100% certainty - of a LEAD rebuild. The one I had came in a stock with the LEAD triangle mark, but no inscription on the receiver leg. It was in excellent condition, but I sold it because I'm partial to the early post-war rebuilds. Those often were reparked over the existing finish, so sometimes over the years the finish acquired a hint of plum coloration. I have such a rebuild, and the purplish tint is way cool IMHO.
