Cast aluminum Model T (?) 19" wheels

[Randy]

I have these for sale on the swap meet page, but can anyone confirm they are T wheels and supply information as to their origin? Set of 5 cast aluminum wheels. They are for 19 inch tires and the bead width is 1-1/2 inch. I believe they were cast in one piece aluminum and then have a steel hub riveted in them.

My first thought is they might be for a truck that has solid rubber tires. Not for Model T and they look to all be fronts? (Too small in diameter)
