Ed Doty switched from a straight-text mark to an arched-text mark some time in 1937. This example constrains the date to some time after February. I haven’t paid close attention to the months on arched-text marks, but now I guess I should.
1931 – Pool

This is probably W. Pool, but for some reason he left off his initial. During this year he also made entirely different marks under the name W. B. Pool & Son.
