I do not know much about these except that they are original from when The Plaza was built. They were removed during the renovation.Please note, they are antiques, and are in antique condition! They are not in any way "brand new" they have years of experience on them and will need TLC! There is some paint, but I did not want to clean them, I wanted to leave them in as-is condition! 2 3/4 Knob lengths, 1 5/8 width. The face plate trim pieces are 7 3/4 x 2 1/2 inches.
