Vintage Gainsborough 1.5" Sonata Crystal Polished Brass Backplate Cabinet Knob.  Lovely knob new in original packaging.  Package was stored in a dusty environment.  I have wiped down the package but there may be some dust remaining.  Please review all pictures carefully.  My home is smoke free and pet free.  Please contact me with any questions.  I would be happy to combine shipping.  Thank you.
