Lost Cabinet Keys (Kittinger hutch)

[Marianne Litzenberger]

Hi there,  I've received a vintage Kittinger library/dining hutch from the 80's but during the move the skeleton keys were lost.  I removed the full-mortise lock mechanism, but there were no markings or numbers.  Does anyone know if Kittinger used standardized locks on their cabinets, and how I might get key replacements made?  I want to keep the original locks in the piece.  I've emailed several antique hardware companies and tried a couple of locksmiths who say they work on vintage hardware but have not yet heard back.  Anyone know of a Kittinger expert or restoration guru?  Thanks in advance.  (I did contact the current Kittinger co. in Buffalo NY but they were not able to help me.)
