Andy I have one that I might wish to part with.
It is a canon Angle Finder C as they are called, and at the time came in at very hefty price, but of coarse I do not expect you to pay that.
I used it for my canon 5D so I expect it will fit the full line of 20, 30, 40 Canon cameras, as they come with adapters to suit the range
You can have it for $175.00 posted to your door.
