Date of Manufacture, Rodenstock, Enlarging Lens

[Peter Collins]

Is there a source for the date of manufacture of Rodenstock enlarging lenses which is based on, or includes, the serial number?

[Bob Salomon]

Yes, just give us the serial number and we can answer your question for any lens they made from 1910 on.
