Joe, if you can make this a "sticky" under the Leica Screw Mount Forum, I'd appreciate it.
I'd like to put together a database of 9cm/90mm Elmar and 13.5cm/135mm Hektor screw-mount lenses in BLACK BARREL only. That means pre-war to the late 1940's. I'm not certain when production changed to chrome barrels but it was late 1940's I'm pretty certain.
Any data I collect will be available to all members who are interested.
The data I'd like to have is:
Focal Length - 9cm or 90mm & 13.5cm or 135mm as marked
Serial number - complete if possible
Focusing scale - feet or meters
Aperture Range - i.e., f/4 - f/36
Elmar or Hektor
Coated or uncoated
Pictures of the lens would be nice; side view and view showing the serial number, model etc.
The names of the owners are not necessary.
Please PM the information or email me at:
doubs43@cox.net.
Thanks to everyone.
