Blue Point raised letter wrench
Posted: Wed Mar 19, 2014 3:59 am
Picked up an old Blue Point raised letter wrench and a flea market. Researching it, I found that it dates from 1935-37. It has an "S" stamped on the back side. This designation was not in the date code chart and was wondering if anyone knew what it meant. I have another old BP wrench with a "1" stamped there that dates to 1941 on the chart, but can't find any reference to any letter designations. Could it be the plant where it was manufactured?
