The other one is a Yankee 131A.   The flat handle one has a switch and wouldn't turn (ratchet) when i first picked it up.   Little bit of lube and it turns one way...only.   It needs a good cleaning inside and out.   I don't consider paint, dirt, and rust as "patina".

Note on that 131A...   almost all the paint is worn off the handle, but it works like a champ.   Previous owner must have loved it some.   

Is it this one?? Gay's Patent Concealed Ratchet (1878)

yup, that's the one.   saw the name one it once the brass wheel finished its business.   can't read the pat date and it looked like some prior owner took the screws out and chipped away some of the wood levering off the metal cover.   

Dumb luck on my part, I opened Barlow's Guide to the screwdriver page , and there it was!!! 

Neat gadgety screwdriver.
