I am offering an old solid brass lock marked Yale on one side and Y & T on the other side.The "handle" is marked Yale & Towne Mfg. Co. on one side and Stamford, Conn. U.S.A. on the other side. The lock comes complete with 2 keys - one the standard Yale Key. The other is a fit fancier and appears to be marked Francis Keil, New York. Both keys work.
