Thank you for the information. I am sorry I was unable to telephone. Please find my appraisal answer below.
The serial number dates your piano to a year of build of 1915 so it is 100 years old. It has some very interesting detail on the cast iron frame (harp). As you have confirmed I can see from the pictures you attached that the internal mechanics are as originally built.
Pianos have a fairly finite life in terms of the musical performance they produce which starts to diminish around the 70 year point. This is due to the wear and tear on the parts as the instrument is played and the natural deterioration with time of the many mechanical parts. This time line can be extended by regular maintenance and tuning and can be considerably extended by a restoration or total rebuild of the mechanical parts.
Save for a few very unique instruments, pianos generally do not become antiques in the furniture sense of the word because they are normally purchased as a musical instrument to be played, therefore one of the overriding factors in a valuation is the condition of the internal mechanics.
Based on the information I have, the condition as described and viewed in the pictures, the name, the age of this Baby Grand Piano and the current markets, I believe it has a value in the $2,200 to $3,000.
