Antique Craftsman / Mission Solid Bronze Rim Lock

This hefty surface mount lock, being solid bronze (or brass?), was typically used for exterior doors although it would be lovely anywhere in the home. It is marked Russwin on the back and the end of the deadbolt is incised Russell & Erwin Mfg. Co. It was likely manufactured in the early 1900’s.

The lock and matching keeper are made of either brass or bronze with a brass color. I find quite a bit of hardware that is bronze without the reddish cast. The metal has not been polished and has light surface scratches that could be buffed out if you wish. The lock is clean and operates perfectly. The replacement skeleton key throws the deadbolt smoothly.  This lock is not reversible and must be used as shown in the photo. Please note that the hole for the doorknob spindle is the larger 3/8” size.
