My book doesn't picture all models. I couldn't locate a picture with the forward slant of the stock like yours. Obviously, they didn't come with the suppressor. Hard to believe the model is not stamped somewhere on it. Good luck though.
I did a yahoo search on Anshutz rifles and found them. They have a contact button and you could email them your Serial Number and a general discription of your rifle. I am sure they can tell you what model it is and which other models share magazines with it.
