I have a Berhardt chest and I wrote the company for any information that they might have about the chest. They wrote back that they needed the 3 digit number that was handwritten on the back of the piece..maybe several times. They said with that number they would be able to tell me when it was made, where, what it was made of and how much it sold for way back when. Sure enough, there are 3 numbers written in crayon or marker. Those might be something like that.
