Remember the likes of Leitz, Nikon and Zeiss were making superb camera lenses back in the Swingin' Sixties, the Zeiss Contarex lenses being legendary.The Dialyt is fairly well sealed against moisture but I'd advise judicious use of a 'damp cloth'. If you can compare it to modern bins (comparable bins) that others may have they may be able to get a feel for what it's like.A silicone shoe-shine pad/sponge works wonders on the binocular's leatherette covering and case, almost like new! If you can compare it to more modern Zeiss bins (8x30 Conquest or 8x32 FL or similar) might also show Zeiss progress.Bird Forum is the net's largest birding community, dedicated to wild birds and birding, and is absolutely FREE!You are most welcome to register for an account, which allows you to take part in lively discussions in the forum, post your pictures in the gallery and more.The manufacturer was Carl Zeiss AG in Jena, Germany.The serial number indicates a manufacturing date of between 19 (1,700,000 starts in 19 starts with 1,980,000) so your's is likely to be around 1936/1937.As to the rubber eye-cups, you may be able to obtain replacements from Zeiss (worth a try). Of course if you compare with a modern Zeiss, you'll feel the 40 years of difference. Of course this depends a lot on which bins you have that you can get you hands on (not just your own but fellow birders too).However compared to a modern binocular in the range of 100-150 €, I think the Dialyt still does look good. Will let you know when they do, I might do a little review and/or pics if anyone's interested in a review of 39 year old bins?
