Petrol lawnmower - for spares or repair (Ivy Farm SK11)

This is an old Honda rotary lawnmower.
The main "deck" is thoroughly rusted through.
The handle is missing at least 1 handle fold / adjustment nut (or possibly two) .
The grass collection "box" would need some serious repair, if it was reparable at all
I believe that the petrol engine still starts (pull-cord) and runs (at least it did in spring 2025).
But the self-propel drive slips so much that it essentially no-longer engages.
