Apparantly this was used from approx 1942-8, then the coloured stamp was used once again. The following stamp was used from 1954-58, this one says copyright 1954. R in a circle and regd trade mark is added below the bunnykins motif, this stamp below dates to 1959-75 on earthenware. after 1967 the following stamp is usually seen, english fine bone china is added bellow the bunny motif as shown here, this stamp dates from 1968-75.
