Moving the business to their North Tonawanda Barrel Organ Factory, from 1914 to 1942, Wurlitzer built over 2,243 pipe organs: 30 times the rate of Hope-Jones company, and more theatre organs than the rest of the theatre organ manufacturers combined. A number were shipped overseas, with the largest export market being the United Kingdom. The first of these theatre pipe organ to be shipped to the United Kingdom was dispatched from the North Tonawanda factory on 1 December 1924. It opened at its first location – The Picture House in Walsall, at the end of January 1925. This particular instrument (Britain's oldest Wurlitzer organ) is now located at the Congregational Church in Beer, Devon. Regular concerts and shows are hosted on the Beer Wurlitzer. The largest Wurlitzer organ originally built (in terms of pipes), was the four-manual / 58-rank (set of pipes) instrument at Radio City Music Hall in New York City. The Music Hall instrument is actually a concert instrument, capable of playing a classical as well as non-classical repertoire. It, along with the organ at the Paramount Theatre in Denver Colorado are the only Wurlitzer installations still in use that have dual consoles. While Denver's is the typical "master-slave" system, Radio City is the only surviving original Wurlitzer installation to have two identical and completely independent consoles playing the same organ. Both instruments have been substantially altered in more recent years. 5-Manual theatre organ consoles are extremely rare, and only three were built by Wurlitzer: Opus 1351 (28 ranks), originally installed in the Michigan Theatre, in Detroit. The organ was removed in 1956 and is now installed in a private residence in Racine, Wisconsin. Six additional ranks were added, to make it a 34-rank. Opus 1587 (21 ranks), originally installed in the Marbro Theatre, in Chicago. It is now installed at the Providence Performing Arts Center in Rhode Island. Opus 1942 (21 ranks), originally installed in the Paradise Theatre, in Chicago. Two other instruments presently have five-manual Wurlitzer-styled consoles, although they were not built by Wurlitzer but were either custom-built or created by combining two smaller Wurlitzer consoles: Opus 2129, now installed in Salt Lake City. Opus 2129 originally had a slave console, and the 5-manual console was created by combining the two original consoles. Opus 1571, originally built as a 4-manual instrument; it was expanded to a 5-manual and is part of the Place de la Musique
