In spite of all the various potential high-tech solutions -- i.e., Google Lens -- I would strongly advise just contacting an antiques brooch specialist. They will know where to look, or may even know the crest from taking an immediate look.
I love the power of technology to make knowledge accessible, but sometimes I feel that we forget that deep expertise exists in people too. There will be someone -- if not a couple of people -- have have likely spent their full life /only/ learning about Bavarian brooches.
