<B>Porter Counterfeit Detector.</B></I> This beautiful antique brass and mahogany counterfeit detector is one of about ten that we know of. Although the date of manufacture is not stated, it appears to us to be of early 20th-century vintage, most likely between 1910 and 1930. The device consists of a brass frame marked with alphanumeric coordinates and two sliding panels on which to juxtapose a genuine bill and a suspected counterfeit of the same type. By manipulating brass knobs, the notes may be moved into positions where their design features can be compared. There is a missing piece, which is a glass plate with graphic squares, as most detectors have had them broken over the years. Included are two "Black Eagles" for you to discern which is an authentic note, however, one might ascertain that the note with "BAD" punched through might not be the one. <BR><BR><B>Important notice:
