Generally, at a glance Id say its a 1927 with the cross bar between the headlights. The 1927 used pretty much exclusively a vaporizer carburetor which has the throttle rod go across the top of the block. A true 1927 block wont have the rod "hole" between cylinders 2&3 nor the hole for the same through the valve cover. Also on that note, the throttle shaft alongside the steering column will only have on hole for a pin for the linkage arm towards the top just below the springs. If theres another hole down lower for the rod that goes through the block, then all bets are off. The '27 didnt have the lower hole but tons of parts have been swapped out over the last 85 years.
USUALLY, the 27s all had wire wheels getting tooled up for the 1928 model A run, but I think wood wheels were still available.
The block number will tell a lot and so will the frame number stamped on the rail top just inside the passenger door. That one is usually harder to read as the rail sprang when stamped. ws
