The Aeolian Company Ltd. in the UK produced an undated 52-page
publicity brochure entitled 'Aeolian Pipe Organs in English Homes',
which contains sumptuous drawings (not photographs) of more than 20
UK organ installations, without identifying the locations.

I have been able to identify just a few of these locations and offer
the information here for those who are interested:

Page 6; op. 1033, Charlton Park, Malmesbury, Wiltshire (house extant,
  organ removed)

Page 16; op. 991, Audley End House, Essex (house extant, organ moved
  to Chirk Castle in 1912)

Page 20; Op. 1057, Warter Priory, Yorkshire (house demolished 1970s,
  organ now in Japanese museum)

Page 22; Op. 1056, Eaton Hall, Cheshire (house demolished 1950s,
  organ broken up for parts)

Pages 28, 30; Op. 1048, Manderston House, Duns, Berwickshire, Scotland
  (organ extant, house much used as a film location)

Page 49; Op. 1081, Ewelme Down, Oxfordshire (house extant,
  organ removed circa 1919 and sold to Alfred Dunhill).

In the booklet 'The Orchestrelle Company and its Business', published
in 1911, the drawing on page 18 shows opus 1097 in Hengrave Hall, Bury
St. Edmunds, Shropshire (house extant, organ re-installed in church).

If anyone can positively identify any more of the locations shown in
these drawings, or has unique information relating to any other Aeolian
pipe organ installations, I would be most grateful to read it.  I also
feel that it is very important that such information should be in the
public domain, via the MMDigest, for the benefit of future generations.
