I found a punch made by a company I hadn't heard of - Lehman, Archer & Lane.


(This is a 7-inch punch that is 1/2-inch hex stock tapering to a 3/16” diameter tip. It is marked "Lehman Archer Lane Co".)
Lehman, Archer & Lane (LAL Ltd.) was involved in the foundation of the British Association (BA) thread form and their tap & die sets are the most common product that I saw in a brief internet search. The Progress Is Fine... blog states that the company dates back to the 1890’s, but I saw another source that said they were founded in 1881. Another source said they incorporated in 1917. They were still in business in 1965. A Google AI pop-up note said they dissolved in 1992.
