Subject: Hensoldt serial numbers
From: "Phil Anglin" <panglin@___rp.com>
I am interested in finding information on the Hensoldt binocular serial number ranges for the various binocular models. Specifically for the period of 1930 thru about 1950.
I am particularly interesting in knowing if Hensoldt started out with a new serial range after WWII. That is did they start at '01" again and go up from there? The reason I ask is because I have encountered many sets of Hensoldt binoculars that I assumed to be pre-war (these were not military coded or deinstglass marked) that bore low 5 digit serial numbers, in the 15,000 to 30,000 range. I have also encountered the same model glasses that were military marked that tend to bear medium range 6 digit numbers (i.e. 300,000 range). I was also curious if Hensoldt assigned a specific serial range for each model that they made. If I could study a sample of say 1000 sets of Hensoldt binoculars I may be able to sort these questions out, of course this opportunity is not likely! Thanks Philip
I have not seen any documentation on Hensoldt serial numbers. If such a list is known, please share it with us. --Peter

The ray shades can be raised. There is the remains of an adjustable head rest to enable comfortable viewing/eyepiece distance. The eyecups are missing. Eyepieces have individual focus. L/H side has a graticule - a circle with a small (+) plus sign in the centre. There is the letter 'T' engraved on one of the prism housings. There was a graticule illumination which is missing. The R/H side is very dirty and in need of cleaning. L/H side OK. There is an open sight for
