Engine number for 1941 Buick sedan

[BuickBob49]

I am trying to determine the Series number that corresponds with the engine number that I have for a 1941 Buick sedan.  Oregon Motor Vehicle Registration information states that the engine number was 44194020.  Sean, could you help?

 

The owner was Conde B. McCullough, state bridge engineer for the Oregon State Highway Department from 1919 to 1937, and assistant state highway engineer from 1937 until his death in 1946. 

 

At work, McCullough drove Buick Roadmasters in the 1930s and 40s. I wonder what model that he drove during his personal time.  His estate's probate records suggests that the car it was a sedanette. What Series could it be?

 

Thanks.

Engine number starting with a 4 means Special, Series 40. If it was a 2-door sedanette, it was a model 46, 46S, or 46SSE.

As Matt said, the engine number is from a Special.

 

44194020
4 = Series 40/Special
4194020 = sequential number, range for 1941 was 4,074,859 to 4,457,940
