Lot of 3 vintage/antique locks.   There is a Reese Protex No. 745 lock, Made in U.S.A. with 2 Reese 503 keys that both work.  Looks like brass and steel.   Next there is an ILCO, looks like solid brass and weighs 11.3 ounces!   The ILCO lock and key are both marked KX0259.   Lastly there is a FRAIM, marked Rust Proof, Pin Tumbler, and Hardened on the loop part, and it has been soldered, as shown in pictures.  The key has a 7 on it.

Each lock and key works.  Please see pictures.  

Nice old locks for your collection or as a gift for a collector of vintage locks!
