So, now we have an "overlap" of serial numbers, as to when the first Lindner mark was used. Earliest example being 1332, with 1569 lacking the Mark, as pertaining to the first Lindner serial number sequence, after the five digit Scott numbers.

Probably a good example of what Daryl noted, with 1332 being released later, after engraving. Is it reasonable to think the mark was applied at the end of the process, right before the gun is released?

Number 001 carries the circled PB, same as both Joe's and my gun, which have the five digit Scott numbers.

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
