Hi MMDers,  This is a rather remote question, but I am wondering
if anyone has knowledge of when the first Hupfeld Helios was built.

The illustration of the style IV is dated as 1908.  I know the early
versions of the Helios have a general date of around 1905.  These dates
seem rather early in the scheme of orchestrion development, but Hupfeld
was a leader at that time.  Any input?

Thanks,
