I'm certain these have a special purpose in life, but have no idea what that is. They are roughly the same size as the standard 1/4" ratchets. Found at flea market for $2/ea.
I have a Duro-Chrome 1/4 female ratchet very similar. I should pester four.cycle about what donor ratchet (s) could be used to convert it to a standard 1/4 drive. At 6.25" mine is kinda long for a 1/4 rat, and I don't have any long 1/4 rats...hmm...
Look up Utica gas pliers...another beautiful tool from back when. Better for screws and stripped nuts than anything made today.
I'll post the part number when I get to the house later
