Yes but don't worry if it isn't.
The important thing is that the crankcase is stamped with a factory stamped number.
Don't forget a factory replacement cylinder would not be stamped.

Number stampings
It seems to have been pre-war Norton practice to stamp the number on crankcase and cylinder flange. It was discontinued once the system of matching engine and frame numbers was introduced for wartime production in October 1939.
Replacement cylinders would not have been stamped and no-one can definitely say that none were missed-off during production.
