i'm not certain how long I've had this particular ratchet, but i have a -v- 1/4 43185 with qr and oil port. black button, chrome selector
FWIW - before our sears closed, in past few months, the tool dept was rebuilding ratchet heads instead of exchanging them.
and i do know, this one is NOT any that they rebuilt for me.
it is marked
-forged in u.s.a. -v- 43185=
-patent pending
