    Re: No vin # on case.

    Under the first case, 148-6136 is often called a belly number but it can also be referred to as a confidential number, a crankcase production number or a line-bore number. Is the same number under the damaged case?
    First 1 is a code number and it was used for 1948 model Panheads regardless of engine size (61ci and 74ci).
    Next two characters (48) indicate model year.
    Last four characters represent sequential machining production. (For 1948 models the sequence numbers began at 1000.)
    Inside the case is casting number 112–48.
    K 7 is a date code indicating the case was cast in November 1947. (Notice the K appears incomplete but I’ve seen several like that.)


    Inside the other case is casting number 24541 55.
    The circled E is a casting hallmark. It represents Eck Industries, Manitowoc, WI, according to Bruce Palmer’s 37–64 restoration book.
    It’s hard to be sure about the date code. What is it?
    Is there a belly number underneath the case?

    I think I see a date code of 8-65 on that middle left case but it’s blurry when I zoomed in. There’s no question that the 48 cases are legitimate. But I would not try to use the other yet to be determined left case as a substitute case. There are people that can repair that case properly.
