Dan Ryan Posted March 2, 2011 Share #1 Posted March 2, 2011 Advertisement (gone after registration) I recently received from Rick this Elmar 3,5-5cm / SN 134079 (pics below) which has been CLA'ds by Reinhardt. Can anyone help me date it? The Wiki has this: SN Start SN End Product Year Total -130463 133506- Elmar 5 cm 1:3.5 (KUP.11-BP+7) 1931 unknown -144221 151035- Elmar 5 cm 1:3.5 (KUP-7+CHROM-7) 1932 unknown Where does Nr. 134079 fit into that sequence - looks like it could be either 1931 or 1932 - it does not appear in either year, but is in the middle. What does KUP mean? Nickel? and KUP.11-BP+7 ? and KUP-7 ? This is the lens: and fossicking about once again, I found what looks like a black FISON hood + a yellow press on filter with the Nr. 1 engraved on the side rim. How many stops should I open up when using that filter? So many questions! Any advice much appreciated. Link to post Share on other sites More sharing options...

UliWer Posted March 2, 2011 Share #2 Posted March 2, 2011 Your lens should be from 1932 still with "50mm" marking instead of "5cm" but already with the focussing lever at the "7 o' clock" position (for older examples it was at "11 o' clock"). "Kup" was the addendum to the lenses name "Elmar" to indicate that it was coupled with the rangefinder. Usually with a yellow filter '1' you should open the lens by one aperture or double the shutter time. P.S.:It's a dangerous lens, for its nickel finish will make you want a nickel black Leica II...

giordano Posted March 2, 2011 Share #4 Posted March 2, 2011 Is it unusual for one of these lenses to have the "German" aperture scale (9-12.5-18) but the distance scale in feet? Link to post Share on other sites More sharing options...
luigi bertolotti Posted March 2, 2011 Share #5 Posted March 2, 2011 Is it unusual for one of these lenses to have the "German" aperture scale (9-12.5-18) but the distance scale in feet? No, normal at all, the International aperture scale was adopted some years after WWII Link to post Share on other sites More sharing options...
Dan Ryan Posted March 2, 2011 Author Share #6 Posted March 2, 2011 Thank you all for the information. I have yet to test it but may be able to do so later today. >>P.S.:It's a dangerous lens, for its nickel finish will make you want a nickel black Leica II...<< Mind-reader!

luigi bertolotti Posted March 3, 2011 Share #8 Posted March 3, 2011 Usually called " Continental " scale. ... correct, and better than "European" given that non-continental Europeans (? ) had used the 5,6-8-11 etc.. from many years (Ross Tele - 1922 catalog) Link to post Share on other sites More sharing options...
