Definitely not Model A, their lens is divided in two sections. I think '32 - '34 sedan delivery/commercial/woodie?
I had a very similar one on a 41 1&1/2 ton ford truck , of course it may have been added at some point in the past
The housing should have 2 lamp sockets in the back, one tail, one stop. The brackets are not 32, that long are likely late 40s or even 50s. If the housings are painted they are pickup and commercial, if stainless they are passenger car. There should be a "DUOLAMP" stamping on the top of the lamps too. Original factory 32 lenses are maked "DUOLAMP" but are flat faced, the convex faceted lenses are either reproductions, aftermarket replacements or later factory replacements.
