Does anyone know what happened to the once-famous Richold Exhibition which used to be on view in the Royal Pavilion (and sometimes the Corn Exchange) during the mid to late 1930s?

It comprised a number of intricate and sizeable fretwork models of well-known buildings, including one of Cologne Cathedral, complete with interior lighting.

Does it still exist and, if so, where?
