During the opening credits of "The Professionals" (1966), starring Burt Lancaster, Lee Marvin, an automobile collects Marvin to bring him to the tycoon, Ralph Bellamy. The story takes place between about 1917 and 1921. The car has the word "Henry" as ascending diagonal script on the front radiator grill.

What is the brand and model of the automobile?

Can't remember the scene in the movie; however, there was a Henry automobile built for a few years circa 1910. Maybe this was it.

From your info the movie was set in a period before the Henry J was built.

Look up Kaiser Frazer the company that built Henry's....in my youth I could have bought one for $500.00 ,but with a new baby and house ....I couldn't afford it ,it was a cool car,nonetheless....BB34
