Thanks for the participation on this question. I find the data very interesting.
Nobody else has mentioned the inspection stamp within the front receiver well on the pistols that have been brought forward. As I said, mine, 2652
i, is stamped with the "Circle N".
Would anybody be willing to take a peek and report how yours are stamped? The discovery of one or more older inspection stamp(s) would add some spice to our discussion.
