The 41/42, according to Jan C.Still, had a total amount of 7,000 manufactured...Hallock & van de Kant, this is from memory, say closer to 10,000...if you consider strictly production quantities pertaining to "rarity", I do not know if I would call it rare.. then again, people bring up the total of 1934 "K"- dates manufactured...also 1937 1st. variation Mausers w/the Mauser "hump", being at 3,206...take your pick...pertaining to the last one mentioned, I am happy to own three such "rare" 1937's...and I will throw in "lucky", too...😏
