I've received this request through the UK Player Piano Group, and
perhaps some MMDer in Europe can help:

Wanted: player action for Steinway-Welte, number 182579, made in Hamburg
c. 1916. The piano has been in the owner's family for 40 years and has
been restored, but its player action was removed before they got it. The
present owner would like to locate a complete Red Welte player action,
or parts, to refit this instrument.

Please contact: Waldemar Raad, Lakenweversstraat 61 A, 6211 BK
Maastricht, Netherlands.
