Hi, just checking back to see if you were able to measure yet? No hurry--as soon as you have the info I can work on completing this for you.
Ok, no problem. Thanks!
Sorry for the delay--thank you for measuring the piano! As I thought, it is not a full 9' grand, though a 7' semi-concert grand is still a wonderful instrument with a nice large size.
If the number you listed above "12359" is the serial, then this piano was built by Sohmer in 1885. It has a beautiful case with the carved legs that you just don't see any longer. Even though there are no specific photos showing the inside, I can see there appears to be significant wear, possibly even rust, on the strings and pins. This is consistent with a piano this old. Often times, old pianos are restored back to like-new condition which is a costly process but improves value significantly. This piano, as you mentioned, is original and unrestored.
In regard to current value, Sohmer pianos were fairly average American made instruments. The company, like many others, has been out of business for many years now. As I said earlier, the large size, lovely case and carved legs are great things and add value well above that of a baby grand. Based on your info and the photos as well as the used piano market today, I would recommend a selling range (private party) of approximately $4,500-$6,500. Expect to take less if sold to a dealer or other third party. I hope this info helps--best wishes and best of luck in your sale!
