Randolph Engineering and American Optical

On the front, Randolph Engineering.  Back then they didn't need big logo.

In the back, the AO Original Pilot.

 Randolph Engineering bridge size emboss on lower bridge

Randolph arm, or bayonet, both left and right bears the same emboss.  In fact, there is no left or right, that's why one (left) arm's emboss appears upside down.

 AO right arm or bayonet from the eye facing side.

 AO left arm or bayonet from the eye facing side.

AO emboss on the upper bridge.

All shots are on tripod.  Unfortunately the arm shots were handheld, meaning, I held the arms of the glasses to move it back and forth in front of the lens to get to minimum focus distance.  Anyway, not the sharpest because of minute handshake.

People are demanding I make a comparison so here they are.  I thought I lost the AO but I actually had it misplaced.  This AO 57-20 is steel color and I have another newer AO pair that is smaller and in gold colored, 55-20 AO on the bridge, minus the USA emboss, on the right arm it says AO Eyewear, Inc.  no USA either.  So I am not sure if AO is still made in the USA, actually with just USA doesn't mean it's manufactured in the USA anyway.
