Now how did that slip my mind? The gauge cluster, found in an old storage building that belonged to my late father-in-law, undoubtedly belonged to him. I know for a fact he owned numerous International winch and 5th wheel trucks during his lifetime. In fact he had three house-moving winch trucks when he passed away a few years ago, a 1937, a 1947 and a 1957. Right now I'm looking out the window at an International hood, sides and grill he had taken off of one of his trucks, probably a 1930s model. You've probably guessed it right. And yes it does indeed look like an International truck cluster. I worked for my father-in-law for several summers and drove several of his Internationals. At least your's is a good enough guess as to where to continue to research. Thanks. Ron
