RTM, I don't know who CV is. Also, I'm at a loss in understanding who is meant by GO and MF. I did see the catalog previously to my post and do concur.
Leviton, Fulton also had drivers with a very similar handle. The ferrule on mine says, " Goodell-Pratt No.5".
Noticing the end if the ferrule on mine is mashed, maybe it is a modified tool. Just wish I knew for sure.
CV was CVAirwerks who posted a few posts above me about it being modified.
GO should have been GP = Goodell Pratt (Stupid Autocorrect & poor proofreading on my part.)
MF = Millers Falls who bought out GP in ~1930.
I looked harder at my handle that looks like Leviton's, and it only says Made in USA, not a brand, but has very similar stitching holding it on.
I have a tool at home with a Blue Point Ferrule, and hand made, not round handle, and a welded together pair of right angle screwdrivers on the same end. Passed on a box of empty ferrules at a recent garage sale, and still kicking myself for that one. Point being ferrules are very portable.
