My 88 year old father has a concertina that we estimate is from the late 1800s, early 1900s. I have some pictures on my cell phone and can obtain additional information from my dad, but I'm wondering where we can go to get information regarding what it's worth, it's origin, any interesting tidbits. We know it was purchased originally by his grandfather. The pictures show it is a Pearl Queen. It appears to have mother of pearl inlay on the buttons. Any suggestions are appreciated. Thank you so much. Karen Adams
