    Do I get the Wehrmacht Awards Award for this ?
    Surprisingly enough, it's not a sticky yet!

      I wonder.
      My neighbour just told me a mad looking fella with a baseball bat had asked him if he was me. Kept mumbling about being web-admin on a site called Wehrmacht Awards and something about an overloaded server.... guess that an award may not be overdue.

          So I came across a pair of E. Leitz Wetzlar, 7x50 Marsept in darn near mint condition. The serial number is 513585. The case as well is almost mint, little storage wear. The "hinge" has delaminated but could easily be glued back together. Does anyone have information of age and or value? Thanks so much!

            three new 7x50.
            one new 8x60.

            Been a while.
            It´s like laying out a puzzle where all the parts are strewn across the world.

            Interesting that the list contains about 10 % of the likely run of the 8x60, and 5 % of the probable run of the 7x50.
            Numbers are too small to really conclude anything, but they would be consistent with a theory that the 8x60 from Busch never really made it to the front line.
            And hence, has survived.

            Or maybe they were taken from the uboats in 1945. Unfortunately, the history of the bino´s wasn´t an issue I wanted to include when I started the list.
            Too bad. The cxn run could actually have been used as a sample for the distribution of the binoculars.

            ( like, how do you count the numbers of fish in a pond? You fish up a sample, like 20 fish. Mark them all, and then release them again. Then you fish up 20 more fish. Now count how many marked fish were among the 2nd sample of 20. From that, you can make an estimate on how many fish there are in the pond.. Larger samples makes the method more accurate.)

            A similar procedure might work with the knowledge gathered in our list of cxn binoculars.

              Great stuff Mike - a true labour of love! But you could argue that the survival of only 10% of 8x60 cxn's compared with the survival of 32% of wartime built U Boats (784 0f 1,156 were lost) might indicate they were issued.

              Statistically (all things being equal) we'd expect to see 73 8x60 cxn's survive - not 21. Of course we must also remember Mark Twain and his saying about "lies, dammed lies and statistics"...

                I have a total of more than 2500 uboats?

                Insane number either way. Denmark had 3, repeat 3, when we closed the sub´s down couple of years back.

                But you have a point.
                A wet dream of mine is to make stats on departure dates on uboats, and compare that with known numbers of binoculars. Just to see if anything can be distilled out of it.
                But then again, I probably get caught midair by someone, who digs out the proper german documents on bino production somewhere.

                Still, nice to think about. And yes, I also like plain puzzles.

                        At least the one in Australia was also in almost new condition.
                        Those above 426700 are most likely surplus sold from storage postwar.

                          interesting to see the 8x60's still fall within the range mentioned by Mike Palmer;

                          I have it on great authority that only 250 were ever made. From 426500 to 426750.

                          Is there any further info in Prof Seeger's new book?

                                New high number. Thank you for the additions.

                                Too bad if someone actually have the data on these.
                                Makes this list a bit of wasted time. If the said info ever surfaces.
                                Until then, this still makes sense.
                                Like how it can be proved they were actually made.

                                Fun to see the picture getting sharper for each new number.

                                I learned the other day someone should have a list of the Kriegsmarine N numbers. But is waiting for a crazy millionaire to come and buy it.
                                Point is, money aside, such a list exist. No one can know if it is unique.
                                Maaaaaaybe some archive has one too.
