I'm very new to Leica and debating how to build my kit. M10 on the way but I have no lenses yet. I found a 35mm 1.4 Leitz Wetzlar for sale somewhat locally but the owner doesn't know much about it. It's not close enough that I can easily drive and test it, but I am considering doing that as soon as I can. Can anyone send me any info on this lens, or what year this serial number would indicate manufacture? I looked at Ken Rockwell's serial number list and it would seem to indicate 1935. That doesn't seem likely. Would love to know how this lens should be priced/valued if it is in GWO. Thanks!!
