I have inherited a cello, which belonged to my great grandfather. As far as we know, he was given it in 1921 - but I know nothing more about its origins than that. It will obviously be going to a luthier to be checked out, but i wondered if any of these cracks are especially problematic. It won't tune as the pegs don't have enough friction, and I'm not brave enough to tension the strings that much either at the moment. The bridge had come off, but I've put that back on (I'm a violinist so not completely unaware of strings). What can anyone tell me about this instrument? Thanks.
