PRH, No way if that cello is in any kind of shape would I use it for a build. Now having got that out of my system, here's a link to one of our members dulcifiddle. His name is Randy Adams,check him out for info.
P.S. I got a brand new fiddle to trade for your cello if you still wanna try it!
I'm wondering what happened with this cello?
my first advise would be to attempt salvage of it, and play it, but if it is determined to be beyond repair, it should make a nice start for some sort of home-built fiddle!
