George Conover patent with the date stamped on the blade holder. Patent reads as follows:
"The advantages of this construction are that the blade-holder is reversible and adjustable. It may be placed at either side of the frame to adapt the blade to cut in connection with the rounded surface or the flat surface of the frame, as desired; and the cutting-blade is also readily adjusted, removed for sharpening, and replaced in the holder. "
Very good overall condition with one replaced locking screw. A very uncommon shave.
