Between c.1903-5 the company used a similar trade mark but changed the initials used from R&S to EB&C the “L” under the knot representing Longton the town of which Foley was a small district. The letter “F” at some time replaced the “L” presumably representing the town of Fenton or area Foley. The EST 1850 refers back to the establishment of the pottery by Mr Robinson. The three loop knot had long been used as a symbol of Staffordshire and many Stoke-on-Trent potters used it as part of their marks.
