There does appear to be a widows peak on the radiator shell, which does indeed look Lincoln. I did a Google on 24,25,26 Lincoln. I can't find any with the hood louvers that come as close to the belt line. This is a 26 Lincoln taken at approxmately the same angle.

I agree with Bob. I think it's a 1923 McFarlan.

Here I thought this one was going to be a piece of cake. I'll flip a coin between Lincoln & McFarlan.
