Nice surface mount interior door rim lock catch assembly. The assembly is unmarked, the manufacturer is unknown.   The door box is in a worn creamy white over original black, with a black catch. The unit is free of any cracks or breaks. The latch assembly works but the top finger lock tab is stuck. We do not have the bottom skeleton lock key.  Shows normal ware for its age, has scratches, and scuffs in the finish.  Overall good, salvaged condition. Please look over the pictures and ask questions when needed. Thanks for looking

Catch: 7/8" wide x 3 1/2" tall x 3/4" thick
