pegging tail

6

I opened up my great-grandpa’s beat-up violin case to inspect this violin. I don’t know the story behind it, but I was curious about the pegs and the inlayed tail peice. Yes, there is a chin rest, but it had been removed and placed in a side container. The label inside is one of Stradivarious ones, but I dont believe that this was made in “1777”. How old might this violin be, and what could the original value been?
