Headlamps for a ? Identify

[Guest]

I have a matched pair (L-R) of Tri-Beam headlamps. I am not sure of the vehicle they might fit to, but here are the details;

Date Stamped in side of the reflector is Sept 20, 1933

Lenses are The Corcoran-Brown Co, Cincinnatti, O

One piece brass, nickle plated body, NO bezel but with a 'relief' notch at the bottom for the lense to be inserted into the one-piece body.

Uses a GE Mazda Lamp 32 & 32C 6-8 Volts

Any ideas?
