I'll post a digression here because no one seems to know the manufacturer code, and the tool has a screwdriver handle:
Craftsman 1/4 drive flex spinner.

Pointed A in the Craftsman logo. Circle V (V) for a code.

The knurled section on the shaft is very much like earlier amber handled versions, but this one should have been made much later. I found several examples online with similar handles, but no (V) codes, and none had the knurl on the shaft.
I have to believe that these were made by a screwdriver vendor, since molding the handle was a much different from forging socket wrenches.
