The newest bunch of MAC tools I brought recently have date codes 1Q axis ratchet and 1N on the precision torque sockets must be 2015-2016 codes.

Dirty,

The 1 = 1st calendar quarter (i.e. Jan - Mar).

I got some MAC wrenches yesterday. The CL20 9/16 combo is stamped with the earlier patent# 3242775 which was for how the open end flats contacted the nut and how the broach contacted it. This patent was issued Aug 1966 to a guy in Glendale CA. The patent 3466956 from Sept 1969 was for the different broach on the box end.

DeadNutz,

Those MAC CL wrenches with those patent numbers are fairly rare.  About the time MAC rolled them out, Snap-on filed patent infringement proceedings against MAC; shortly thereafter MAC withdrew these wrenches.   SHF

That was the 1969 patent. I have a CL stamped with the wrong patent number of 3466955.

Good price?   Lets see the tools.   The boxes certainly the wear of lots of miles.

Price was $150 for all.  I'll take some pics this week.  Reamers, deburrers galore, files, end mills, and some stuff I'm not familiar with.

  Here is a MAC 3/8" drive ratchet set I picked up at a garage-sale Saturday. Very plain with no plating at all. I guess I should find a case for it. I am guessing this is 50s? With no plating it must have been well cared for to not have gotten rusty.
