Hi Sven and Mod CJ,
After much consultation between Jack and myself offline we both came to the conclusion that your Air Cowl with the starter has probably been changed due to a failed rope and thus for many mower shops it was just easier to cannibalise a dead engine for it's bolt ons so as to quickly fix another that's come in the door.
So with that your identifying details have been lost forever. We all agree that the engine block would still be the original to the chassis, but in the end it really doesn't make much difference at all does it and if we hadn't identified this no one would've ever been the wiser.
Cheers,
BB.
