Hello dansblackcat

It is a rare treat to see a first model 45 20" in such original condition.
The previous owner must have looked after this one - and no big dents in the
catcher ... Remarkable!

As you probably found, there was only recently another 20" 45 project:-

I personally would like to see a photo of the mower number plate to
add to our records and the provenance of your machine.

SB expert Mod Bonnar Bloke should like to see this one.

All the best with the resto.
