T.C. Lewis & Co. bouwde in 1901 opus 620. Een nieuw pneumatisch sleepladen-orgel voor de Tentoonstelling (Exhibition) in Glasgow (Lanarkshire) Schotland, UK. In 1902 plaatste de firma extra zinken frontpijpen. Later werd de Exhibition omgedoopt in Kelvingrove Art Gallery & Museum. In 1962 is het orgel gerenoveerd door Henry Willis & Sons. In 1989 werd het orgel gerestaureerd door Noel P. Mander. Hierbij is het niet gewijzigd. Het instrument heeft 48 stemmen, 3 manualen en een vrij pedaal. De stemmingstemperatuur is evenredig zwevend. De toonhoogte is C = 517.3 Hz.
