If my memory serves, the two "bands" around the cab below the windows were pre-1940, maybe 1936 or 37.
The cab and fneders look like they are salvageable. Don't know about the engine, but there may be some clues about that engine being a lot earlier than you might think. Maybe just the photos, but the push rod cover, mechanical linkage for the starter and such don't look like stuff outta the 40's.
