From: Ian McIver, July 1999
I do know of one organ that had a Tibia Tierce included as original, that
being the 3/10 at the Granada, Kingston, England, which was a rebuild of a
Style F with Brass Trumpet and Sax added and Clarinet replaced by Krumet
(also had a grand piano attachment added) and acquired a new Opus Number.
It opened in November, 1939, and had the Tibia extended up to 1 3/5.
Reginald Dixon opened the organ, so maybe that's where he got the liking for
that pitch. A few UK Wurlitzers had Tibia Tierces wired in later, but as
far as I know only Kingston had it on the relays sent by the factory.
Along with the Granada 3/8 Wurlitzers, Kingston had a full range of
intra-manual couplers, so with those in use and the 1 3/5 Tibia, it could
get very bright at the top end...
