This used Large Corner stamp was made by Basic Tool Company. It is tool number 256. This Corner stamp is a great example of their craftsmanship. The impression measures 15/16" in length (along each of the two "corner" sides). Stamped on the tool is "Basic Tool - U.S.A." and "256". There is some corrosion on this stamp, including on the tool face. These old tools do not come available very often, so don't miss your chance to add a great tool to your collection. It still has many miles left in it.
In the late 60's and early 70's, the demand for stamping tools reached a frenzied level. This created an opportunity for some new stamping tool manufacturers to be born. One of these companies was Basic Tool Co. They produced stamps under the name Basic Tool USA and Basic Tool L.A. to fill the demands of the time.
