Picked up a great big Keystone ratchet set yesterday.  Female rat, square plug, two male/male extensions, 18 double hex sockets, and 8 8-point sockets.
Haven't been able to find a whole lot about them--it seems they disappeared some time after WWII.
But in my exploration, I came across a pic of a much smaller set with a hex drive.  The thing I want to bring to your attention is the picture that includes what seems to be  straaaaange hex to square wobble adapter.  Fourth pic down.

Ever seen one like it?

Are we sure that belongs with the kit?

Hmmm. Can't be certain, but the more I stare at it, the more it looks like hex-hex instead of hex-square.

I gave up on being sure of things in 2016.  To answer another post, I still believe it is hex to square.  Probably.

All I have is an empty box found at an estate sale. I saw a set with the same number once on line and it was square drive.

I think I have one of those swivels around here. I wouldn't know where to look to find it but I thought mine was a hex to hex. I see them every once in a while at estate sales.

Hello, I emailed the site that had the photo of the Keystone set. Here is the response "Hi, I've lost track of that set, but I enlarged the image and I'm sure it's hex to hex- pretty unique!" Regards,Lou

Thanks for clearing that up!  But it would have been way cool.
Here's a strange twist, though.
The ratchet handle from the Keystone (out of Buffalo, NY) set is a dead ringer in shape and size for the handle of the Skinner inner seal saddle tee drilling device (out of South Bend, IND.) I found last summer.

What's up with that?
