I looked some more and found a 1929 Pontiac Big Six with the wire wheels and dual side mount spares. The wire wheels were throwing me off as much as anything, with most of the cars I found having wooden wheels. So, it may be 1929.I am outta my depth on sleds this old. but i looked at a few ... didnt find any Pontiac coupes with side-mounted spare till '30. body contours looked similar from '28 though (spare on rear behind "rumble seat" tho).
that said, IF they said "circa 1930" (vs. saying the 20's), i could give them a pass
Here's a '29 Big Six with the same wheels, top, flip out windshield and rumble seat.
