I do not know where you can get the proper grill cloth, as it is a Canadian radio and there are not enough of them to warrant
making reproduction grill cloth.
One place you can try is” Richmond Designs”, in the States. I have dealt with him and his grill cloth is good.
You might find a pattern that would work for you.
As far as the chassis of the radio is concerned, I don’t know at what level you are at ,for restoring it
I get my capacitors at ”Just Radios”
You can probably get the schematics from ‘Nostalgia air.
To start with change at least the electrolytic capacitors, but i always change every cap.
Good luck
