Mk.II Forend cap

I live in South Africa where Ross rifles are most uncommon. Over the years I've managed to obtain four, one of which I had to import from Canada. My most recent local acquisition is an early Mk.II. Unfortunately it has been crudely sporterised and then roughly used. I have set myself a project of restoring this rifle. There is one problem. It is missing the forend cap. There is absolutely no possibility of finding one locally and I'd be grateful if somebody in Canada could let me have details of a dealer who may be able to supply the part. I attach a photo of the version that goes with my rifle.
