Gentlemen,

Thank you very much, everyone for your advice. I have talked to the owner of the rifle and shall meet him this weekend. Sorry for mistaking the rifle for what it isn't - you are absolutely right: it is a low wall in 32 Winchester with an octagonal barrel. But again, I haven;t seen the rifle and hope to check it out and buy it if all goes well.

Thank you again and I shall post after talking to the owner this weekend. Good hunting, everyone!
