Just went surfing a bit and found lots of examples of these items, except no music box. Not sure much about the company could find little about that, but did find mass with these hallmarks. The price was all over the board. $5.00 to $39.00, which sound like it has little value, but is very collectable Because yours has a mucic box that may make it a bit more special. I'll call that vintage collectable, most likely $25.00 Ebay price at the right time to the right person. $40.00 at a shop or on consignment. Will look a bit more at the hallmarks but most likely will yield anything of intrest,found pieces into the 90's so I bet they still produce. But take me with a grain of salt, the big boys will be back by morning and will give you better more experience detail, This is my second month of adding porcelain to my knowledge.
