Well not to take anything from John and Charlotte Goins and there wonderful encyclopedia of cutlery but that book is from 1986 and certainly they didn't have all the information that are available today. Droescher indeed made razors in Cranford, New Jersey but that factory opened in February 1917 and it was called Cranford Razor Works.

The trademark on these razors was The Cranford and the razors were clearly marked with the Cranford razor works on the back side.

There is many mentions on the internet about Droescher making razors in Cranbury, but I find no evidence of that.
