I know that tools stamped, "Mechanics Tool and Forge Co." can be as old as 1938, but were some tools stamped this way into the 60s?

The very long screwdriver in the thumbnails got me wondering about this. Note the odd stamping: there are two sets of "Mechanics Tool and Forge Co." and "Sabina O." One Mechanics Tool and Forge Co. stamp is almost completely off the edge of the ferrule. Was the ferrule sheet metal stamped as sheets before being formed?

Is vintage MAC more centrally located/found around Sabina, OH kind of like Plomb is primarily a West Coast brand? I know there are collectors everywhere now, but before the internet, some brands just didn't make it very far out of their original production region. I haven't come across much in the vintage MAC brand, but I do have a complete metric combo wrench set from 6mm-24mm. I prefer their version that just precedes the "knuckle buster" series.

I got this combination wrench set (No. KC5A) as the receiving end of a trade with @RTM last year, neglecting to post it here in the MAC thread until now. He did upthread, but I will elaborate.

Note that the largest wrench, the No. C5 (1/2"), is branded exactly the same, in the same style, format. and placement as the others, but i's forged-in, whereas the branding on the others are stamped. All the wrenches have the sizes forged-in. Note that it also has a double-hex (12-point) broach, whereas all the others are hex (6-point) broach. I have little to no doubt (and, given the circumstances of its finding, no reason to doubt) that all the wrenches are original to each other and the leatherette pouch. I suspected it was assembled in a transition period and I am very confident that was sometime in the late mid 1940's to the late 1940's, prior to 1952.

The catalog excerpts below are from the Mechanics Tool & Forge Catalog No. 47 (published in 1947). The model numbers on the wrenches ("C1" through "C5") match the model numbering scheme in the catalog. All the wrenches in the catalog have a 12-point box end, but we know from a larger combination wrench set (No. KC11) that @Oldtuleguy acquired, linked here, that the smaller wrenches (C1 through C4) were made with a 6-point box end broach.

Interestingly, OTG also has the same No. KC5A set as this, linked here. In his set, though, the brandings on the No. C5 wrench are stamped, just like the other wrenches. At some point, I'm assuming all the wrenches had forged-in brandings, and it might've been earlier.

While the combo wrench set pouch is not shown with the branding in the catalog, the open end wrench sets do show it, also helping to date it.

In the 1952 catalog, the combination wrenches have two different part numbers "CWx" for 12-point and "CHx" for 6-point.

Have no idea on the age or practical use of this 3/4" curved wrench... Just thought it would be fit nicely on this page. About 13" long. Markings on one side are "S 93" .. Mac wrench (1).JPGMac wrench (2).JPGMac wrench (3).JPG

I found a plug/adapter with no manufacturer name. I'm wondering if it might be a Mac tool?

It has a 9/16'' male hex (with a detent ball) on one end and a 3/8" male square drive (with a detent PIN) on the other end.
The only marking is "A-318"

I'm trying to figure out who made it. There are two reasons I'm wondering if it might be MAC:
  1. UserJohnDeere posted a similar looking plug here (but with a different part number): MAC V18DA
  2. An old ebay link to a pair of MAC adapters shows part numbers that are kinda-sorta similar.

Any thoughts? And why/when did MAC use square to hex adapters?

Here is the one that I found:

I think it's Apex. Good quality piece.
Dang - you're a genius. Thanks for the identification! Still currently being made. I'm surprised there is still a need for this. Who has sockets with a 9/16" hex drive?

Thanks 3bay.
