I received this type 1 Sargent 79 in with a bunch of other old tools this week. It seems to have a stamp on the iron that was from a period prior to the production of this model. The type 1 was in production from 1910 to 1918 and from my research this stamp was used from 1902 to 1909. This particular plane has the owners name and 1918 engraved on the sole. In the 1911 catalogue this plane is shown with a later stamp....has anyone observed anything like this?
