My wife's dad and two brothers bought a used 1928 model A in 1933 so "they could pick up girls". The pliers that came with the car had circle M after the ford logo, not the McKaig Hatch circle MH on the opposite jaw. I did see the circle M on a wrench on the Ford Museum site from 1917 so it goes back to the Model T days. Anybody know what it is?
My "family heirloom" is satin silver on the jaws and patina light rust on the rest. This is not some rare antique and I see a lot of them cleaned up to a nice dull silver. What method do you recommend, rust remover, wire wheel, for minimum damage?
Was the wrench you saw the one mentioned in this discussion?
I'm kicking myself. I saw a chart showing all the common marks used by tool makers in the Model T era, but I failed to save it. Maybe somebody who's a better searcher than I am can find it.
This site looks like a likely place to find tool information, looks like a neat museum.
Here's a site that has a few. Images appear lower on the page. Click on the image for slightly larger view.
Here is a group of pliers that were made over the years. They are from various forgers but the circle M is Moore Drop Forging as seen spelled out on the Ford Monkey wrench (in next post). It has the circle M on the opposite side of the company name. I think that the pliers on the left are the oldest ones. I don't think that any of the ones except for the far right were ever painted. The ones on the far right are English Ford and were painted black.

Ken, & all,
Yes, the Bolts Tool Museum is a neat museum--I was in charge of setting up the building it is now in, although the present set up has been really altered by Mr. Bolt and his volunteers. They're pretty good a finding out a tool's manufacturing history if you ask.
