It must be kept in mind that some patterns remained in production and usually kept the same number for many years.The trade-marks were, however, changed several times between the 1880s and now, and these can help to establish the period of production.Hand-painted, and largely hand-painted, wares designed and decorated by Robert Allen and artists in his studios, were often given RA-numbers, written by hand, in addition to the usual trade-mark and any other number.
