Found this :
Hello. I found the S.I.R mailorder catalog from 1986-87 that has the rifle i am looking for in it! It is a Canada Scout 22cal revolving carbine. It has a 19-3/4" barrel and is 35-3/4" long. The 6 shot cylinder swings out like a normal revolver and they had one version in 22cal that shoots lr,l, or shorts for $245 and another one that comes with a second cylinder in 22magnum for $294. They had a lot of nice 22 rifles in their catalog back then including a 22cal semi auto version of an ak 47 and a 22 cal semi auto copy of a thompson machine gun with a 30 rd and a 50 round drum magazine and a 22 version of an m16 made by a company called Squires Bingham. If any one knows anything about the canada scout revolving carbine please let me know. I tried google but didn't have much luck! I will try to post a picture of it when i figure out how to do it.
Cheers RJ
