We had a Ronisch piano at school in Yorkshire identical to this, it seems to have been a classic Art Nouveau style. One aspect I do appreciate is the peirced top door with cloth on the reverse.

Upright pianos are traditionally shoved against a wall, have heavy solid panels on the front and the tone is vastly inhibited as a result. I did see a new Steingraeber upright with a very modern take on this idea however. > The extra spring on the jack is quite common on higher end Bechstein actions and on Broadwoods.
