Full Mortise replacement lock, plate, key, screws, for desk, trunk, cabinet, NOS

Description

The full mortise lock, Key and Plate sets were salvaged from a woodworking shop many many years closed.  The writing on the lock is NLCO which my research says that it was a product of the National Lock Company.  There are small spots of corrosion on some of the outer metal probably from fingerprints.  These are listed as New Old Stock.  All work and are ready for installation. I found the steel mounting  screws after I had listed this so the last photo is of four screws that are for mounting these locks. These will be included. I have other parts like these that are not complete.  I may list those when I have sorted them. Any interest let me know.
NOTE* The item(s) in the photos are the actual item(s) you will be receiving.  The item in this case is being sold as NOS. I run a satisfaction guarantee agreement between all buyers. If you are not satisfied just send it back within 30 days for any reason.  I will arrange and pay for all returns.  Refunds are set at 100% money back upon receipt of the item sent you.  There is NO restocking or handling fee.  Thank you, Be well, Karl
