Question: Where to get Music Man Cutlass battery compartment?

My Cutlass sat in its case for awhile. When I just took it out and wanted to put the battery in I noticed that those tiny little prongs of the battery compartment’s inner lid where broken off. Can’t figure why.
Anyway! Here’s my question, I hope someone can answer:

Where do I get a replacement?
I live in Germany.

I’m not too keen on buying a third party spare part (if there are any that would fit) since the original compartment is stamped “Music Man” and I’d prefer to get one of those.

Thanks in advance,
