Hello. As I have a 490 Touring, 1916, I take the opportunity to give you some information:
The radiator apron looks familiar, but originally the Bow-Tie was painted on the metal. However, many(including me) put on the metal shield instead
to brighten up the front.The fenders are not 1916, as they do not have the shape of that year.
The headlight holders look familiar.
The engine is not a 16, as the top on yours is covering the valves. The number stamped on the outside, on the circle of the flywheel can tell which year if the wheel has not been changed during the years. The fan is not same as mine, while the knobs on the dash are right, same with the size of the missing odometer. The 16 has only 3 doors, I believe(only 1 in front. The left pedal is first working as clutch then as brake, while the right one is a parking brake. To help you better, I will send some photos of mine.
And yes, you should try to rescue this one, even if quite a lot is missing.
