But bear with me now, and try to keep an open mind about this . . .
"Stratford Pen Company" was the later incarnation of Salz Brothers, Inc. One source I read somewhere said that the company was set up separately by Ignatz Salz, and eventually purchased Salz Brothers. Ignatz died in 1958, and the company may have continued on for a few years after that. The earliest Stratfords I've seen, until the Chicago show, appear to have been from the late 1930s and loosely copied the lines of the Eversharp Doric (complete with a little gold seal that instead of a double check mark had the number "77") .
