I am assuming this is an upright Circa Wurlitzer made in 1930 . A similar model was sold here for £300. https://santamaria-ca.americanlisted.com/music-instruments/upright-gulbransen-piano-circa-1930s-300_26296029.html
Some are going for more like £500. Others are being given away for next to nothing! (£35 or less!)
It depends entirely on the condition of your piano, not just what model it is.

I suggest you pay for what is called a "blue book" valuation of your piano. You can do it all online and it costs around £25. http://www.concertpitchpiano.com/Appraisal.html

specifically what do you want to know?
the SN shows 1921 date.
Have you tuned it this year? If the piano will not hold tune to A=440hz, the value would be 0. However, I would think it would hold 440...but I may not.
Call your local piano technician to check it fully.

For $20 these people will do an appraisal .
They say they are a Grand Piano site, but have uprights and baby grands for sell, so I'm guessing they do any piano appraisal. Won't hurt to ask.

no fixya doesn't do appraisals which is done by hands on and visual

Serial numbers between 360400>383000 were produced between 1925 & 1930. Actual value is determined on many factors which cannot be accurately estimated without a professional viewing and "hands-on" contact with the instrument do to its many working components, care and condition of the instrument and of coarse playability.
