A M Co, is Athol Machine Company, one of the early names for the company that produced Athol vises. They were later taken over by Starrett but still used the Athol name for a number of years afterward.
I had a vise like that at one time. Interesting in that the rear jaw is the dynamic jaw.
Are you sure it is not a Number 71?
