Looking at a 14" dagor F7.7 with a serial number 397XXX.

This chart (http://motamedi.info/serial.htm) does not contain numbers in this range.
Can someone point me in the direction of a list that might? Or perhaps share insight on this?

If Goerz American, made between 1918 and 1927.

If Goerz Berlin, per P-H Pont made between 1915 and 1920.

Why do so many list a lens or any serial # as 123XXX?

Is this an attempt to conceal provenance?

I see this often and wonder...

inches instead of millimeters? On the older ones, if it says serie III nstead of Series III, its european.

'14" focus' is the tip-off. US-made.

Garrett, I don't know much but I have a good library.

I've put up a list of links to all of the library that's on line. http://1drv.ms/1w0vbMD I added new information to it yesterday, you might want to visit it.

Thanks Dan for the information.
