Upright Piano

This piano was always in the music room of my Great Grandmother's house.  It is an Emerson upright, Black, with beautiful scroll work on front and ivory keys.  There is only 1 chipped key.  The strops on the hammers are leather and need to be replaced before it can be tuned, but there is only one cracked hammer.  The tuner said they write the date they tune a piano on the inside and the last time this was tuned was in 1927.  He also said it was one of the heaviest harps he had ever seen in a piano.  The lid is hinged and when opened, becomes the sheet music holder.  In the middle of the open lid it says Emerson Piano Co. and Boston underneath (all gold lettering).  My Great Grandmother broke up housekeeping at age 96 and lived another 12 years!  I inherited the piano at that time.  No idea what it weighs - took the movers 2 hours to move it into my house (I think they were from the 3 stooges moving company!) and made the entryway stairs crack under it's weight.  Not sure what the average weight of a piano is, but this is heavier.  Will it be de-valued if I have the strops replaced so that it can be used for lessons?  Still in relatively good tune for being moved 3 times and not tuned for 81 years!
