Re: Barbour Silver Co/International Silver Co

Barbour Silver Co was a legitimate Co. You mention that is indicates, "Quadruple" and no mention if it Indicates "Quadruple Plate" which would indicate an authentic Barbour Silver Co. Piece. I would have it appraised to authenticate. A lot of companies where imitating makers marks and flooding the market with forged pieces for their own personal gain. Most likely your piece is Silver Plate as Quadruple Plate woud not be the mark for High Quality Silver such as, 925/1000 fine, with 75/1000 of added metal, usually copper, to give it strengh and stiffness. Use caution and do some research before you purchase any item of substantial cost. Hope this helps.
