This fun vintage Walter Lampl sterling heart (1940s) lock is one that is not often seen. The heart lock measure 13/16ths of an inch by 5/8ths of an inch. The back is marked sterling and WL for Walter Lampl. The back has been engraved with the name and date, "Al" and 2-14-43 (Valentine's Day). This lock does require a key to open. Condition is very good with light surface wear. This guaranteed to be a period charm and is not a reproduction.
