Hi,
A couple of years back
www.charlesandson.co.uk said he had these in stock. They were about a fiver each, I think.
I sprayed mine with Plasticote (black, satin) using the primer for plastics first. So far they look ok. A couple of them have a little paint missing but they still look better than the original.
