97 would indicate a 1949 but the F series made their debut in the model year 1948. The 7H indicates a 6 cylinder and C a 1/2 ton commercial model. Ford had inconsistencies in numbering their light commercial models. An example is that the 1949 and 50 models continued the same prefix. If it is an F1 then it would likely be a 1949 or 50 model. Pictures are worth their weight for ID purposes.
PS: the 7H must indicate 1947 for the engine design year & H is the model of the engine. The H model superseded the G model in 1947.
