The mysterious "MF" branded socket

[Tom "Python" Aycock]

Good morning my fellow GJ tool enthusiasts!

I found this 1/2" drive 5/8" 12 point socket marked with a serial # 5915 and a boxed in MF makers mark?

I checked MasterForce but those sockets all have the name spelled out fully. Nothing from Miller's Falls looks remotely similar.

Could it be Millers Falls? I know they made sockets, but I don’t recognize that logo.

Millers Falls sockets were pretty late as well, Late 70s early 80s if I recall correctly. There are some posted here somewhere.

Checking the Miller's Falls thread reveals exact same MF squared logo on some ratchets and sockets...so I've got my first Millers Falls socket!

I was thinking Massey Ferguson when I picked these up today, not Millers Falls.

Yeah that was my only guess
