I'm new here and hope this is the right place to post this. Please pardon me if it isn't.
This breastplate has been sitting on my father's pump organ in the dinning room for at least 50 years and my mother wants to 'pass it along' but I don't know anything about it. I've searched but can't find anything like it and my father is no longer able to give any kind of help as to who, what, when, where or why. Could somebody please point me in the right direction?
Thanks!
I've added 2 more photos, in case they might help. Thank you.
