Hi,  Keith Prowse still operates in London, UK.  It was originally
a supplier of barrel pianos and also an agent for Hupfeld.  They
supplied many of the large Hupfeld Helios instruments to skating rings
and dance halls in the UK.  This ceased as of 1914.

They produced all sort of music items and were musical instrument
dealers.  Today their business is by name only and they are theatre
and concert ticket sellers.  See on-line.  There has been quite a bit
written about them.
