Looking for dust cover or rain cover

I have a 1977 Crossley 32, and I am looking for a dust cover or rain cover for the car. Anybody have any ideas on where to locate one.

I use a plastic tap. Crude but effective. Weight it down or if you are in grass use tent pegs

I used the cheapest small suv cover. Works great but not visually appealing

I was thinking about something for a smaller boat or canoe.
