The available information to hand indicates that the original Wurlitzer was not identical. Apparently, Dixon (after receiving complaints from dancers that they were unable to hear the organ) re-designed the instrument, which was subsequently rebuilt. It appears that there were some additions made at this time.
In any case, if the organs were identical, why bother to transfer it six years after it was first built?

Dixon transferred to the Empress Ballroom after the Fire, THIS organ contained 10 ranks from the ORIGINAL Tower organ which was enlarged and re-built with a new console to 13 ranks and installed in the Empress Ballroom in 1935 as the new TOWER organ went in. The two organs were IDENTICAL from 1935, even having the couplers changed at the same time. The Tower Organ later had the Vox removed and a Solo String (Gamba from the Opera House Wurlitzer) and Tuba Mrabalis (also fromt he Opera House) added.
