Have the opportunity of buying a nice pair of Zeiss dienstglas. I have found out from the serial number that it has been produced in the early 30's. The binocs however have the H/6400 marking. Was is used that early??? Apart from this, there is a small "m" letter under the serial No. From what I know big "M" stands for "Marine" issue, correct? But what does a small"m" mean???
Thank you for any help in advance
