Slumlord ....you are funny ! Idaho ...... your Post reminds me of a Garage Sale I went to a few years ago . I asked if they had any Hunting or Fishing stuff for Sale . Guy takes me into his old Barn and shows me a Target Scope up on an old stone wall . Had red stuff all over it . Seller thought it was Rust and wanted $40 for it . I bought it , cleaned it off with some Solvents and all that red stuff came off . It was like new with perfect Glass . Can't remember exactly , but I think it was a Lyman 20X . Sold it to a friend who Collected old Single Shot US Made Rifles . We were both happy .
