Hi, I would like to ask you how much could cost my Viola. I’ve got it 32 years ago as a gift from my grandpa, who was a viola player, teacher, conductor and director of music school. What I know from him that this Viola was made by one of the student of master Stainer in 1776. This Viola is a small size, unusual, chamber size. It has small crack on the back. Also this Viola I’ve got with very old case, shaped like coffin ⚰️, made from wood, very light, but that time I was shy go around with case like that, and I changed it, and old case threw away. Please, any thoughts to evaluate my instrument?
