Finding an exact match for an old lock is not always possible, as only a limited amount of sizes are now made.
Drop In Locks with 3/4" backset, are authentic replacements for furniture made in the 1900's. Use on drawers and doors hinged on the right. Designed to drop into a pocket cut by a router or machine. Once installed lock should fit tightly. It will be encased with wood on both sides only selvedge edge will show.
This is a very reasonably priced lock, as such: locking mechanism is average, not as smooth as finer made brass locks, yet is serviceable. Made in Asia.

Keyhole location measurement is critical. Replacement lock-keyhole-location must match location of keyhole in furniture.
To measure: easiest to measure old lock, if you have it:
Lock Keyhole Location: distance between selvedge-edge - where bolt shoots through, to lock pin. This measurement is known as the backset.
Furniture Keyhole Cutout Location: distance between furniture-edge to estimated location of lock pin in furniture keyhole.
This lock fits perfectly thanks to Paxton's informative website (it's amazing how many companies don't show measurements of their products). It completes a nice piece of furniture I bought used that just needed a little touching up.
