1978 Low arch Charger, Not all that common to see in that colour, but definitely more of a parts mower in that state.
Looks like mostly engine parts and the cowl, the cowl you could re-sticker and put on heaps of mowers of the era, that cowl was well loved by Victa at the time.
Engine should be pretty standard for parts, 160cc I believe, standard S70 MKIV setup, Rear facing with a G4 carby.
