I have a very old 912UL from a Europa (980 hours). The engine serial number is 4153138. The serial number on the gearbox housing is clearly visible as 10336? If anyone can help me with confirmation / original configuration info regarding this engine as it left the factory that would be greatly appreciated. Also on the side of the crankcase is marked Rotax A 2195 and then the numbers 6911 723 L1 but no obvious crankcase serial number in the format described in the IPC. How do i conclude what serial number this crankcase is and therefore which serial number range this crankcase set belongs to?

Thanks in advance for any help!
