The scope complete with Carrying Case (which you are apparently missing) would fetch $1K CAD. The unique folding Tripods are actually harder to find than the Scopes themselves and can easily fetch $1500 CAD. The chances of finding an orphaned Carrying Case to complete your scope are slim to none, which affects value. I'd place the value without the Carrying Case at $500-$600 CAD.
I bought and sold C Mk1 scopes as recently as this past summer, and they went for $1K in decent condition (with the protective Case).
