Hi Lawnewb,
Well it seems as though you've managed to find a fairly good honest mower that's not had any bodgey work or modification made to it.
What you have there is the very last variant of the Rover Model 45 with the rearward facing clutch lever opposed to the earlier forward pointing made unit.
I've got to ask you how did you manage to get the powder coating off so easily as that's the big bugbear with these Rovers, yes they can look good but underneath all that powder coating lurks heaps of metal cancer just waiting to surprise you.
A electrolysis bath would remove all that rust on the deflector really nicely and thoroughly to the core.
I'm sure you're aware of one of these as I feel you've read my thread on that rusty verti-cutter I built and commented on at the end ?
Ultra-Colour make a pretty close Red in a spray can that will match up nicely to the rest of the machine.
Cheers,
BB.
