how important are the crankcase serial numbers?, where they are exactly (can share pic) and what characteristics they must have to simulate originality?

The vin number is on left side of engine, line bore numbers on bottom on engine.
Some vin numbers have been altered, we can tell when that is the case.

In America they are vitally important. In your locale perhaps not so much. As to characteristics they must follow certain layouts with characters correct for the era in which they are produced. There are far too many variations to list them. Look in the knowledge base for examples.

Collectors always want 'the real deal', so unaltered VIN and matching belly/casenumbers.
That said, as Robbie already mentioned, in some countries they just pay attention to the VIN...even if selfstamped..
As long as you can prove it's heritage, it'll be ok.
Police forces pay extra attention to altered VIN numbers.

If you're building a chopper or custom and the casenumbers don't match, it will still be okay as a rider.
There are a lot of selfstamped/altered (blank) motors out there, be sure what you buy.

Hûh?? A 1950 Knuck??
Does such a beast exist, I thought the Knuck was already surpassed by it's successor in 1949 ?

1948 was the first year for the 74 inch FL series of Panheads. 1948-52 were the last years for the 61 innch EL Panheads. There were also FL and EL Knuckleheads until the 1947 production year. That 50 EL numbered case is a Panhead....

if these two numbers are identical, is it good ..., a symbol of originality?
