There were others, including Thomas Lee (of Pead and Lee) and later John Lawson of Rodney Lodge Warehouse, which was listed in a repertoire in 1803. Others were Branton – Ross and Joseph Wilkinson – Co (see below). The exact number of colours and colours that were active in Hull in the late 18th and early 19th centuries is almost impossible to establish, as early commercial repertoires are very unreliable and one has tended to repeat the mistakes of another. Similarly, not all companies have entered the directories, as shown by the lack of entries for Branton – Ross and Joseph Wilkinson – Co. Therefore, the number of companies, to guess, is a matter of success and miss, although it seems that, from an early number of about four or five, which was in operation at the end of the eighteenth century, the number continued to increase in the 1830s and 1840s to reach 10 on average and did not fluctuate much until the end of the 19th century. The industry employed surprisingly few workers, and the 1851 census showed that only 200 men over the age of 21 were employed in the paint industry. However, early census information should also be treated with caution, as it is likely that many more unofficial agents were used occasionally, as well as dozens under 21 years of age. The later figures are puzzling, as entries in commercial directories for colors and men of color, i.e. manufacturers, often contain color merchants, stores and color agents under the same title. It is safe to say that this is already an anti-competitive market that the Sissons brothers received in Hull.
 Nicola`s Giacomo (Notes on the Museo Nazionale of Florence-V. Fragments of Two Series of Renaissance Representations of Greek and Roman Heroes, The Burlington Magazine XXXI [December 1917]: 224-228) describes “an image that belonged to the Dowdeswell brothers, whom I know only from a good photo that was kindly shown to me by Mr. Berenson. This table should also be added to the series. Everything agrees, except that the lower part of the base on which the hero is located no longer appears after apparently being cut by a reduction of the panel to the ground. The author also speculates that this painting could be one of two paintings in the series that were at the Florence Art Market around 1890, information that was recorded in the 1893 catalogue of the work of Luca Signorelli and his school at the Burlington Fine Arts Club in London. 1851 Ann Johnson, beer merchant, No.7 Bankside1855 John Clark, Sculcoates Inn, Wincolmlee1867 Wm.
