Welcome, Leroy. Please don't be a stranger .
1941 engine numbers began with, 4,085,000
1942 began with 4,457,941
therefore your's is a 1941.
The 7 prefix digit is the series digit. All pre-war engines had this as a prefix. Post war, 1946 and later, the series digit became a suffix.
Hope this is clear. Information obtained from "reference" on this forum.

The seven makes it a seventy series. Roadmaster, then.
