Old snap on ratchets, snap on guru needed.

[Hammell]

I inherited some old snap on ratchets, 1/4 drive ratchet and long handled 1/2 drive, any idea how old they are, tough to read any makes other than snap on. Ive seen date charts but theres not much to go from.

The 1/4 drive looks like its stamped CAN for Canada I would assume. GM-70-M is what it looks like to me the G could be an O?

The 1/2 looks like it has a 7 or something on it.. pat no 1854513

Thanks for your help

Between the lever,look for a year mark when they were made.Look up that year mark on Snap On's yearmark sheet.

1/4 Looks very similar to this one(GM-70-M). http://www.thegaragegazette.com/index.php?topic=5532.0

The patent was issued in 1932 http://www.datamp.org/patents/displayPatent.php?pn=1854513&id=34779

Could it be one of their first reversible ratchets?

For the 1/2 ratchet I see between the on and off switch there is an E. Is that it? 1944?

Yep..Someone in the thread posted that the date code was between the on/off labels. Looks like the 1/4in has something in the middle too..but hard to tell what it is.

I actually had them rebuilt about 12 years ago. Pretty cool I think.

I had some Canadian wrenches that didn't have a date code, not sure if that goes with the ratchets also?
