Meanwhile, back to the paperweight. When Brian Slingsby and Judy Taylor were putting the Whitefriars book together, sample of these 50's weights were shown (including those mentioned below). The main ones of this type that are seen are the fairly common coronation weights that show EIIR, and the less common Triplex.
Both of these are done by taking a central button which is blue over white and scratching the letters/numbers onto it before it is set into the weight. I have one which has three initials, and someone has one with 1954 (I think off the top of my head). The suggestion was that the factory were not averse to turning out the odd weight with intials (although whether these were official, done for staff, done as friggers - who knows!) , and so it is very likely that GHEW was just a person's initials. It is not known how many of these there may be. I have only seen a couple over the last 10 years so they are very rare
