I can't remember if those with the metal placque were stamped. Check them over thoroughly for a made in usa/date stamp. Matco might be able to give you a ball park on age with the serial numbers if you can find someone that cares.
I had a side box as well as a middle box that had the metal plaque and both were date stamped, but according to a former Matco dealer none of the metal plaque boxes were date stamped. Maybe they stopped half way through.
