While digging around for some tool catalogs I am going to give Twertsy for his website I came across a National Garage Tools catalog put out by National Machine & Tool Co. with a price list from 1948. Address is 626 North Mechanic Street, Jackson Michigan.
Some Google research did not turn up much. Adding the street address changed things though as the building was occupied by Zoerman-Clark Manufacturing in the 1950's apparently. That led to a Worthpoint find, a Zoerman-Clark Thread Chaser model number U-130.
I had seen a picture of a thread chaser in the National catalog so I looked it up and it is the same, Axle Rethreading Die No U-130.
So apparently National either had a name change or was sold to Zoerman-Clark. More hunting ahead!
