Came home with no-name ratchet, new to me.

[Northwoods]

It is an old 1/2" female ratchet with no spring.  Mine is an orphan based on the 1927 Hinsdale patent.  It works on a rocker system to engage the teeth.

I am sure you old hands are familiar with it, but I had never seen one like it.
Mine is more substantial than the one pictured.  Again, it is 1/2" square drive.  It is 9 1/2" long; the business end is 3 3/8 X 1 9/16".  It has a heavy cylindrical knurled handle.
It came with a (similarly unmarked) 3" male to male extension instead of a plug.
Anyone here ever seen one or know anything about it?

[J.A.F.E.]

I had one similar that was SK and have seen the same one unmarked.

[Northwoods]

Boom!  That is mine.  Unmarked, as is this one from AA, but was found in a set with an
SK decal on it.
The only difference is that mine has 2 3/8" of continuous knurling instead of the three bands as in the picture.
Thank you so much!

I'm pretty sure that I have a couple of these in a bucket somewhere. Unmarked.
