I came across this ad while looking for something completely different, and I thought it might be of interest to someone. I found it in a Canadian Machinery Magazine from January 1912
That is a neat find. I'll print up one to go with one of the wrenches next time I display them.

Here's one of mine that I didn't give to Martin Donnelly to auction.
That is a very nice example!
Thank you, Noel!
