Hello,
I've got this Goerz Dagor Series III No.3 with f/6.8 and a focal length of 8 1/4".
Because the focal length is given in inch and it is inscribed with "Goerz Dagor" only - not Goerz Berlin or C. P. Goerz - I guess it was made for the US market by the original Goerz (maybe US fab).
The serial number 222830 seams to pe WWI (1905 - 1910).
Might this be correct?
What is the angle of view? I've read 72° (90° at f/32) but I'm unsure if this is correct...
best regards,
Oliver
