It's 2017 - went up just over a week ago. Old Moore's Almanac will give you further details.

You likely have a set built between 1919 and 1930. If you go to this site (
The history of the telescope the binocular ) and scroll down (or search) to areas with Zeiss Binoculars, there are a number of files that have the information on runs. In my case, I looked at the Spreadsheet attached to the Zeiss Binocular Models entry, which , between lines 150 and 168, notes that binocs with the Lena logo were made from 1904 to 1945, and that serial numbers above 1 million began in 1919 and above 1,550,000 began in 1930, putting your pair in there more or less in the middle.

Cheers!

Google several vintage binocular web sites like this one:

and check Ebay for similar items.

I have a pair of 10x40B T*P* line. What's the date and worth of these if anybody knows

Carl Zeiss Jena is East German manufacture, that is why you don't find it in the Zeiss catalogue (it isn't Zeiss). It is also almost certainly post-war, as there was no East Germany before WW2.

Carl Zeiss Jena made inexpensive optical equipment for export to the West. The optical quality was fairly high, but not as good as the West German Zeiss, and the finish was less good.

Unfortunately if they are out of alignment you need to take them to a service center. It can't really be fixed at home without a device known as a collimator. Binoculars can fall out of collimation if they have been knocked or dropped. Jenoptems were made by the defunct East German Carl Zeiss Jena. Zeiss was split in two after WW2 with Jena being on the east. The current Zeiss firm is the West German company. Zeiss Jena ceased to be after the fall of the Berlin Wall. It is unlikely that the current firm would fix these for you. If they did the price would be greater than several pairs of Jenoptems.

Before you do take them check to see if they have a seven digit serial number. If it is six digits they are fake Jenoptems. There were many fake Jenoptems sold in the eighties by UK dealers. There is even a myth that they were made under licence in Japan. A myth is all that information is. There is no documentation to substantiate this and was probably spread by sellers trying to legitimise an inferior product.
