I have an upright, straight strung, piano in fully working condition, pre-1950s, a tad scruffy, previously belonged to a colleague whose mum was a piano teacher.
One string has a slight buzz when you release it or nearby keys, it's probably the E below middle C. The tuner tweaked it to get rid of this, but it came back, I think it's a dodgy damper but it should be curable.
Free to anyone able to arrange transport from Burton-upon-Trent area. Movable by two strong and willing folks, three to lift up into a van. I'm willing to assist.
