Fox Patent Dates -- I've never really studied this carefully, but I just looked at all my guns from 1922 to 1929 and they all have the roll stamp with seven patent dates --
PAT'D AUG.16-04
AUG.1-05 OCT.17-05 JAN.16-06
MAY.11-09 MAY.2-11 JUNE.11-12.
On at least two of my guns they started the roll stamp too far to the rear and came to the breech face before they got the numbers after JAN and JUNE!?!
Guns I have from 1910, 1912, 1913, 1914, 1918 and 1920, all have a different roll stamp that is smaller and reads in the other direction --
PAT'D DEC 2 1902
AUG.16 1904 AUG.1 1905
OCT 17 1905 JAN 16 1906
On the 1920 gun this roll stamp was struck so lightly that you can only actually read the top line and the 06.
A gun from 1906 only carries --
PAT'D AUG.1 1905
OCT.17 1905- JAN.16 1906
Those patent dates of DEC 2 1902 and AUG 16 1904 are patents that were originally assigned to Philadelphia Arms Co., and A.H. Fox Gun Co. didn't have them until they bought out PAC in late 1906.
Finally the very early A.H. Fox Gun Co. guns have --
PAT'D AUG.1 1905
