Picked up a tray of sockets and ratchet handles at a swap meet today. Among these were five MAC 3/8 drive 6 point sockets with interesting markings. The markings on the sockets all start with XM then it is 19-6, 18-6, 16-6 and 15-6, all followed by USA. I have no idea. Also picked up a Bonney USA MT18. I think this may be a metric socket.
The best of all was it also included an American-made Husky 1/2 drive with sockets from 1/2 to 1 1/8, all 12 point, an 8" extension and a 9" and 14" pipe wrenches all for $22. The irony is I already have that Husky set and have had it for eons. But I knew it when I got it today. Can't have too many tools!
