The specification was as follows: Specification E. J. Hopkins, in the first edition of Grove's Dictionary of Music and Musicians, comments on Schulze's exhibition organ and describes the Lieblich Gedackt as “the invention of Schulze....singularly beautiful in quality of tone”. The Flauto Traverso he describes thus “double length in the upper part....the pipes being of wood bored and turned to a cylindrical shape were in reality so many actual flutes”. In addition he noted that the organ possessed two excellent free reeds. The exhibition organ did not by itself produce any orders for the firm and it may have been Hopkins’ personal familiarity with some of the German instruments which finally clinched the Doncaster commission for Schulze. Hopkins visited the 1852 Schulze organ at Bremen Cathedral and was later to recall: “The effect of the organ was exceedingly solemn, grand or soothing, according to whether I used the 16 and 8ft diapasons, the full organ, or the flutes and gedackts. In fact, I never at any organ, in the whole course of my life, felt myself under such a great enchantment. Indeed the excitement was so great that I had two or three times to leave the church in the most urgent state.” Writing in The Organ, its History and Construction (E. J. Hopkins and E. F. Rimbault, Third Edition, London 1877), Hopkins describes a specification for an ideal 4 manual organ of 87 stops which bears a close resemblance to Doncaster. The order was placed in 1857, originally for a three manual instrument. With the death of Johann Friedrich Schulze (1793–1858), it was left to his son, Heinrich Edmund Schulze (1824–1878), to take over as the innovative and creative force within the firm (see plate I). Edmund Schulze soon persuaded Rogers to enlarge the specification to a 5 manual instrument which was to be the largest church organ in the country with 94 registers over 5 manuals including 25 stops on the pedal department, exceeded only by Willis's organ for St. George's Hall, Liverpool of 1851. In 1860 the main consignment of parts from Germany arrived at Hull. Much of the construction took place in the church itself where Edmund Schulze together with four or five men worked on the project for two years. One observer reputedly noted that the large 32 foot principal was cleverly made from the wooden packing cases of the shipment itself. According to Rogers,
