I didn't need to do much to this one, a little soap and water, mineral oil, and a sharpening, took a nice edge.
I didn't pin down the date on this one, but it is a Dwight Divine & Sons so it puts it from 1923-1941
If it was Dwight Divine & Son it would be 1900-1923
I found this advertisement for the 1502 for 1933
The earlier 1502 had a nice long pull.
