S/42 questions

Hi bill,


i have a K-dated S/42 with no. 5057 s.

How many have been produced with K-date and wich numbers and letters were used?

I heard that there were only 15.000 made in 1934, is it right? How many are left over today? Wich was the first serial-number given to a K-date? Wich letters were used?
