Hello Jay, You've got a valuable, rare and nice binocular. It is also a very unusual example. I maintain a small Leitz binocular serial number database (the Leitz microscope serials cannot be applied to binoculars) and 431011 is a mid-war Leitz number, probably 1943, post-war numbers not beginning until about 480000. After World War II, Voigtlander began single coating the Heliar lenses. Serial numbers starting about 2,7xx,xxx on, appear to be factory coated. Tronnier of Voigtlander, tweaked and recalculated the f/3.5 Heliar and created the 105mm f/3.5 Heliar with coated lenses (US Patent 2645156). Araldite wrote: Have you looked on the box. Yes, the serial numbers are on the boxes (as well as on the lenses themselves of course). Fortunately I haven't mislaid any of my lenses or had any stolen, but I was just curious when Vermont3133 wrote that authorized Fujifilm dealers include the serial numbers on receipts. Sep 10, 2011 These binoculars i picked up at a yard sale, im interested in learning more about them, on the left shoulder it says: voightlander underneath it says braunschweig under that is a serial number capital N and underlined o, and the numbers 62810. On the right shoulder is marked the number 6x24 and above that is an etching of a lion on a pedestal.

Here is a quick and easy way to get the year of manufacturing of Leica lenses (L, R, and screw mount) based on the serial number which is located on the front of the lens:

Update: A reader just sent me another way of determining the production year of Leica cameras and lenses: just got to this website, and type the serial number.

And another update on the serial numbers after 2004:

The following is a collection of serial numbers for large format lens manufacturers. For the most part, the information has been culled from Wilkinson, Glanfield and Wrights' magisterial Lens Collector's Vade Mecum, a data base available on CD-rom. Other sources of information include web-pages and anonymous information passed down to me through others.

There is a real absence of information on large format lenses. Of the contemporary makers, only Schneider has made a great effort to provide information, the other lens makers have been less forthcoming. However Rodenstock serial numbers, the other major European manufacturer, have been posted by Kerry Thalman. There are a few web-pages, both official and unofficial, for other three manufacturers, Congo, Nikon, (Unofficial and Official) and Fuji,(also here). However, serial numbers are, to my knowledge, entirely lacking.

Zeiss no longer makes large format lenses, and consequently has little interest or incentive to provide this information. Goerz, and Ross are long gone, and Voigtländer exists only in name. Taylor, Taylor & Hobson is also gone, although its one time subsidiary, Cooke, has recently returned to the fold, and is now making a 4x5 portrait lens. In any case, none of these companies provides any sort of information regarding the lenses they once made. This page is a modest attempt to provide one form of information, serial number-year correspondences.

Caveat: While I would like to make this collection as accurate as possible, I cannot make any claims as to the accuracy of any of the information. If you find something which you find of questionable validity, please do not hesitate to contact me. Or, if you have any information on large format lens serial numbers, for the manufactures list above, or any other, kindly forward them to me, and I will attempt to incorporate them.
