More images. The mulching bar is 19 1/2" inch. There is plenty of corrosion on the blades; not particularly deep though. Does anyone recognise what brand it may be? The front axle looks to need replacing. Judging by the pitting, the plug is as old as time. The wheel bearings are all naff, especially the front ones.
I water blasted it and surprise, now it doesn't start. A day drying thoroughly then I will check for spark, fuel.
