John M. Mossman Lock Museum

The John M. Mossman Lock Collection is housed at the General Society of Mechanics and Tradesmen of the City of New York building at 20 West 44th Street in Midtown Manhattan, New York City.

Egyptian wooden-pin locks, Chinese padlocks, American time locks, etc., are all displayed in lighted glass cases on the second floor of the General Society.

Alongside the cases are studded trunks, with cleverly concealed keyholes, once used by bankers.

Collections of various antebellum curios, rare books, prints, flags, clocks and medals have also been donated by friends and members.

Admission is $10 for viewing this museum collection, which is open to the public.
