I've never seen or even knew they made a wood stock Calico. I do however own three of them, the .22lr in pistol and rifle, and the 9mm in pistol. I never found a 9mm rifle at a price I was willing to pay.
Here's another odd one I own, although I don't know if it qualifies as rare.

It's a PKP (Powell Knife Pistol) in 38spcl. Picked it up many years ago for $400. I've never seen another one although I've seen pictures of them in different calibers.
