Up for the offering re these 2 Antique Keys for winding your old Pocket Watch/s.
They are approx 1 7/16" long.
One has no markings and the other has RIVtd PIPE on one side and "5" on the other.
Hard
to see in the pic - the letters "td" are capitol letters
(with a dot
under each letter) but smaller in the font size then the "RIV"
I think "5" might be the size but not sure.
