The company was founded in 1826 as a partnership between members of the Pilkington and Greenall families, based in St Helens, Lancashire. The venture used the trading name of St Helens Crown Glass Company. On the departure from the partnership of the last Greenall in 1845, the firm became known as Pilkington Brothers. In 1894, the business was incorporated under the Companies Act 1862 as Pilkington Brothers Limited.Wikipedia

Pilkington's history has been extensively documented so I won't do it again here. See:

Pilkington Coat of Arms

Pilkington Brothers trademark
Coat of Arms: The Pilkington arms consist of an argent cross patonce voided gules. The Pilkington crest has a mower with his scythe and has a legend that an ancestor of the family, being sought at the time of the Norman Conquest, disguised himself as a mower and escaped. —Wikipedia

Motto: Now Thus, Now Thus: The surname Pilkington was first found in Lancashire at Pilkington, a township in the parish of Prestwich-cum-Oldham, hundred of Salford. This distinguished Saxon family held a family seat in Lancashire since before the Norman invasion, traditionally escaping after the Battle of Hastings by posing as a thresher and hiding in a barn under hay and the flail hit first on one side and then the other, hence their motto 'Now thus, now thus' and the Family Crest of a mower.House of Names, which cites Mark Anthony Lowe's 1860 Patronymica Britannica, A Dictionary of Family Names of the United Kingdom.
