Oh, wow! Lots of replies after a busy weekend, thank you everyone
. Theres lots to think about now, just to confirm its a good piano, a Rogers London upright that has been regularly tuned and well looked after in its workings. Its been recommended to me by my childrens piano teacher, and he says its in tune, as he has played it many times and knows who is getting rid of it, because their children no longer play. Its for my children. who are currently muddling along on a keyboard and facetime lessons, so its our first piano. It has already been painted, but desperately needs a facelift. Until I have it brought home, I can only go off pictures, but I will need to replace the missing support, which isn't affecting its performance as the keyboard is well integrated into the body of the piano.
The reason I was thinking of painting it is because its already partly done, and I thought with good quality preparation and paint, it would be the best way to get a good finish. If, after sanding it, its showing signs of looking ok to just varnish or laquer then I would consider it.
I'm taking my inspiration from the beautiful pianos in the Piano Shop, Bath, and The Little Piano Store, although I do realise they are painted by experts, not little old me. They do sell as painted in F and B though, so I'm bit thrown by the comments that it won't be playable after painting? I am pretty good at painting, careful and attention to detail with excellent prep, if I do say so myself 
I was also thinking of polishing up the peddles, and either rstoring or replacing the name letters/decal.
Senora - thanks for showing your lovely piano, I like the idea of doing the inside of the lid a slightly different colour. Clever dh of your to fit it in the alcove for you, I would love to put it in an alcove but we have built in shelving in one room, and the other rooms alcoves are too small, so I'm not exactly sure where its going to live yet. Did you take off the lid and panels when painting? I was wondering if I should take off as much as I could , prep, paint and reassemble to get the best result and make sure it can be got at properly to be retuned?
Wilteddaffs, the Tim Minchin video was great! Unfortunately I've not got a Yamaha....
Pinkyparrot - I was thinking of putting piano sconces on but its a very simple and plain design with quite clean lines and I thought I might make it look a bit out of place.
Itsdinah - would you be happy to show me a photo?
Sinkgirl - does the eggshell paint leave fingermarks? what else would you recommend? I've used f and b modern emulsion on walls, and I think our cupboards are F and B eggshells in all white, they seem ok, but I grant its not the same as a piano ?
Develsko - have you got any tips as to what to do with it?
Thanks all!
