Antique Russell & Erwin (Russwin) brass mortise locksets, manufactured in New Britain, Connecticut, are highly sought-after, durable pieces of American hardware, often dating from the late 19th to early 20th century. These sets are paired with crystal glass knobs.

This listing is for 2 mortise locksets and includes everything in the pictures.

There are no keys and I cannot confirm the lock operates due to missing key.
