Title: Bergman wrenches
Post by: gibsontool on April 29, 2019, 10:33:10 AM

Does anyone know what years the curved Bergman wrenches were offered?
 I've looked at Alloy Artifacts but they don't have very much on Bergman tools.

I don't know how long they made them, but the patent was applied for in 1919 and issued in 1921 according to DATAMP.

Thanks Noel, never thought to check Datamp.
