Any idea of the vintage of this set? They look like 1/4" drive sockets, but the drive is actually .277. Just large enough that a modern 1/4" socket wont fit it. Found it pretty interesting...

Most of the pieces should have a date code stamped on them.
If the stamp looks like an E, then the date would be 1944.
If the stamp looks like a G, then the date would be 1945.
If the date looks like something else, then you need to consult a date chart.

Thanks, looks like 1945 based on the G stamp. I'll share this with my co-worker who asked me about this originally.

9"32 is almost useless today if you had just a ratchet but having a set is cool. I think I heard you can put a 1/4" rebuild kit in one of those but I dunno. It's a nice find I've seen others ask about same ratchet and heard of people grinding the square down to fit 1/4 and no way would I ever do that one. They use to have a couple size drives back then that they did away with I can't remember other size buts it's closer to 3/8 or 1/2 it was in between the 2..Boy I couldn't imagine trying to did through a bunch of loose sockets back then trying to find one to fit my ratchet.

These were produced for the war effort. The 9/32 drive size was so they wouldn't wander off, into the civilian world.

There IS a drive adapter you can buy so you can use the drive tools with 1/4 sockets.

FWIW.

I believe 9/32" was rather standard before 1/4" took over. If I recall correctly, looking in 1930's SO catalogsorry, they only made 9/32", no 1/4".

There was a 1/4 SO rat made in the late 30s. GM-70-N quite rare.. The other 1/4 dr tools were made starting in about 1944. There were 9/32 dr tools made into at least the 60s, mostly industrial.

The adapter I have is the other way around, as well so they can go both ways. lol
