Thanks John,
The Monte Carlo stock was a mis-statement on my part. It is correctly called a "cresent cheek piece". Since posting I have found out this is what appears to be an Anschutz "Rook Rifle", though I am still waiting for someone to verify that. I e-mailed Anschutz directly with photos and hope they will get back to me with confirmation.
If it is what it appears, then I need to find out the value. I saw listed recently on GunsAmerican.com a listing for the same rifle in a larger caliber, (Stalking Rilfe), for $850. Hope this thing is in that range.
Thanks again,
Phil
