The subject has come up before. No dates on these
That style was made back in the mid-1930s. It continued until at least 1960. It was labeled “Blue Point Supreme “. Snap-On wrenches, other than some specialty wrenches, started being labeled with the Snap-On designation in 1948 on combination wrenches. Other styles continued to be labeled Blue Point with a gradual transition through the 1950s. That may not help with this wrench, but that is a timeline you can go by in general.For what it's worth
My uncle has told me that he and my Father bought a set of these in the summer of 1947. With the exception of several special service tools, these were the first Snap~on Logo wrenches and were likely prototypes, no dates and no catalog record. Could that be correct?




I agree, ‘35.I saw a nice speeder with the locking pin recently, only it had the knob handle. Seller and I didn’t come to an agreement.
Found this adaptor today. An early A2, 3/8 to 1/2 drive.
1930’s I believe. I’ve stared at the date stamp and can’t decipher it.
EDIT: maybe 1935
At first didn’t notice the A2 running the other way above the logo. The detent hole is what drew my attention to it, had to figure out what old brand it was with a hole like that.

I see the small spatter, and the grinder marks. But the pin is original to this model number, and the exposed steel looks very consistant, with no color or grain seam.It looks as though the square drive end with the retaining pin has been welded on and then the weld ground down.


Easier to see in the photo than in front of my face.I agree, ‘35.
A socket welded on there would explain it. Likely someone wanted to fix a socket on there which didn't have a hole in it to suit the lock on pin.I see the small spatter, and the grinder marks. But the pin is original to this model number, and the exposed steel looks very consistant, with no color or grain seem.
Maybe a socket was welded on, then removed.
The solid knob is different from the big hollow one shown in two eBay examples. I wonder if this is inside those “doorknob” types, removed fron this one. It seems very short, and only a small band knurled.

Someone else on another site suggested a fire hydrant wrench.Looks like a Chrysler emergency brake adjuster, only bigger. Snap-On made tools for the railroad. Maybe something along those lines?

Fiddled on Google and my my guess is it's a combo wrench. There are picture of one end and they say its a Valve Persuader.
I think the question has been solved for the OP. That tool would give you the leverage you need. I was not familiar with the name OS&Y valve, but, heck I have seen them lots of places.The valve persuader is for use with larger water/steam valves. The kind with large cast iron wheel handles you see in sprinkler systems (OS&Y valves) or industrial applications. You feed it through a spoke and hook the valve stem with the U shaped piece. You can use leverage off the tool handle or a bit of hammer work to break the valve free. The other end looks like a hook spanner for removing large caps. Like hydrant caps or something similar.
I remember seeing these in older snap on catalogs. Sometimes those big old valves can be a ****** to get moving.

I think that might be as close as we're going to get.Fiddled on Google and my my guess is it's a combo wrench. There are picture of one end and they say its a Valve Persuader.

For bonus enjoyment scroll down and there's pictures of strange valve persuader / adjustable combos.
The other end of your tool I can only speculate. Seeing one end is for valve service maybe the other end is a valve compressor for a Model ??? engine.



Nice! The 9/32” drive set is amazingly complete and quite valuable!Just picked these up at a flea market for $8 total. Hard to find vintage cheap tools around here.
