Looks like possibly an engine swap at some point in its life. Case-match stamps usually of that vintage were a smaller, and shallower stamping. Does the engine have a reed-valve or is it rotary-valved? Pics of the flywheel / carburetor area would give some of the 'eagle-eyes' on this site more to work with and possibly give you more info.

Agree that more pics of the motor, including the swingarm where the serial #s go, and while you're at it just the whole scooter would be helpful to understand the context here.

Could be dealer replacement cases.

Piaggio would provide unstamped cases (and frames) to dealers to replace damaged/destroyed scoots. The frames would have the prefix stamped. However the engines cases (that I have seen) did not even have the prefix stamped. I have a set of ET3 cases completely unstamped.

FWIW, YMMV, etc
