I found a few numbers for reference:
Engine Block - 72804Z & 099 90
Cylinder Head - 230
Air Filter Assembly - 440

Possibly it was made for export as the Caution stickers is in English, French, Spanish & German.
Hope this helps.

As it runs well and seems to need only minor fixes I'm thinking to make it my first restoration. Needs a new flywheel and cut height adjuster bracket so if anyone can help out please let me know.
