Hi Group,  In 090817 MMDigest Petra Zenker asked about the two
Rönisch serial numbers: 61516 on the soundboard, and 41289 on the
player. I would also be delighted to learn more about this type of
instrument.  Perhaps somebody can identify its "birthdate", from
the serial numbers given.

The "Pierce Piano Atlas 10th Edition" says: "Rönisch, Carl, Est.
1845 in Dresden, Germany.  A new Factory was built in St. Petersburg
before Carl died in 1893.  Carl's sons Albert and Hermann took over
the company.  Rönisch made pianos for Ludwig Hupfeld before they
joined forces in 1918."

Serial number 61516 would have been between 1910 and 1915.  1910
begins with 50800 and 1915 begins with 63200.  Serial number 41289
would have been between 1905 and 1910.  1905 begins with 39000 and
1910 begins with 50800.
