    Yes. The larger flywheels came out in 1940.

    according Palmer's:

    1936-1940=8-1/8" diam. 61 only
    1941-1952=8-1/2" diam. both 61 and 74

    They were probably made already end 1940 but the larger wheels first came out in 1941 for both 61 and 74 in the short rib case version as well as in the long rib ones..
