  White porcelain and cast bronze trim accompany these restored mortise lock sets manufactured by Niles Chicago Co. with signed patent dates of  June 25, 1878 and May 18, 1880 on the locks.  Escutcheon plates measure 5 1/4" x 1 5/8" and the white porcelain door knobs are 2 1/4" diameter.  Niles Chicago patented and used an unusual door knob with their locks that do not operate on a spindle but mount easily and directly into the patented Niles Chicago lock - if you are unfamiliar with this type of lock, mounting instructions can be provided.   This type of lock is extremely effective and efficient when mounted.   Locks are reversible,  restored, and complete with strike and each lock has one key as shown below.  Backset is 2 1/2" - brass lock faces are 5 1/2" x 7/8".  Comes with slotted screws for mounting.
