K-3 International Milk Truck

In the movie, Elvis pulls up in front of a beach house in his Manx and in the background is a K-series International Milk Truck. Although the truck only serves as a backdrop in the scene, I would like to find out more about it. I think the truck is a 1941 International K-3. I base this on the truck that I have come into possession of which matches virtually all the details of the milk truck as seen in the movie. Would like to establish the ownership chain and history for the old truck. Thanks, Bill Parkman
