    To start I had no idea how pianos work until I got this piano. but I am not afraid to teach myself new things.

    Had the chance to get this square grand piano, My wife fell in love with it, most of the keys did not work but I said how hard can it be ... *que laughing* If anyone has any information on this particular brand that would be swell, so far my research has taken me to that they were a piano retailer and maybe had someone else make these for them. They won some awards at the 21st Ohio state fair best square piano silver medal. found in the 26th annual report of the Ohio state board of agriculture.

    So far I have replaced the back rail felt, balance rail felt, front key felt, hammer rail felt, replaced all the thread on the jacks, replaced all the dampers, (not period accurate dampers as i have learned after reading many threads on here), I fixed one damper arm on the piano.

    what I still need to do is replace the 2 last missing treble hammer assemblies, eventually replace all hammers and all strings. For right now I am just trying to get this to play well enough for my wife to enjoy, I have done two tunings on the piano so far at A435 seems to hold tune well just still slightly flat (piano has been sitting for many many unknown years)

    Questions I have. I have a substantial gap below the nameboard and the keys, as well as when the key is depressed the key sits 1/8 to 1/4 above the front rail cloth and the jack is just pressed up against the jack stop button. and I get roughly a little less than 3/8 key dip so far. MY guess is the back rail cloth is too thick that I got as the piano had little to no felt so I had no examples to go off of. If I add more punching's to bring the key height up I will have even less key dip. I am just unsure where to start to get this piano as good as I can knowing it will not be perfect.

    Below is a link to all photos I have taken so far and will update the album as i add more.
