Rotary snow plows

Just a bit off topic, but looking for pictures of 5 rotary snow plows. Any information on these plows would be greatly appreciated.

I have a few pictures of the Grande rotaries but would really like to see any more. I have no pictures of the others except a bad shot of the tender of RGS 1 in the Kaslo & Slocan book.

Thanks all,
