This showed up in my mailbox today...It was part of an order thatI sent in back in March...I forgot that Sarco had put it on back order...
I tried looking at their web site today...But they seem to have pulled the "Luger Parts" page down...IIRC, this was advertised as a "Breech Block, used, stripped"...but it came with extractor + spring & pin; firing pin + spring & plunger...and it looks used, but the outer surface looks a lot like the re-finish on my Russian capture P38...
I'll be passing this on to a fellow who wants a complete LP-08 upper assembly...
I've been stung by "parts kits" from Sarco in the past [2004; 1911A1 parts kit], but this didn't turn out to be as bad as I expected...
