Checking on the nitro finish, trapeze like some of the old Gibsons, part of the nut missing and some obvious body damage.

Kingston Guitars... Made from 1958 to 1967. Guitars imported from Japan by Jack Westheimer and Westheimer Importing Corporation of Chicago. Early examples made by Guyatone and Teisco. My 2011 Price Guide does not show any prices for the acoustic models, which is kind of strange. It does show prices for the electric models. Your Kingston may be from another manufacturer.
