Antique C & R Dipper Concertina

Hello there. I was wondering if maybe anyone could assist me in finding some information about a newly found concertina. It was in my grandmothers "collection" of goodies. She has long since passed, so unfortunately I am unable to find out its history. But after research, I'm very much aware that it was initially ordered and loved by someone, at some time, some time long ago. I know my grandmother most certainly didn't play any instruments, let alone a concertina! Anyhow, if you could offer any knowledge and/ or approximate worth, it would be much appreciated.

Thanks so much, in advance
