(Walter) Derek Blundell was a UK author & modelmaker active in the late 1960s and into the 1970s. His books were, perhaps, nothing special but in those days there wasn't much choice.
His models were advertised in magazines like 'Military Modelling' and he would produce anything to order. The pricing was simple - I think it was GBP 1.00 for every hundred foot of length, plus postage. I ordered only one, the frigate HMS Lincoln and was, err, disappointed.
Anyway - Sir Patrick Wall's collection. Wall had been a career member of the Royal Marines but left in 1950 to pursue a political career, serving as a Member of Parliament for many years. He led a very active life with many interests but what concerns us was a collection of some 6000 models of ships & aircraft.
Following a stroke the collection was placed in the Museum of Army Transport in Beverley, E Yorks, close to his home. I saw the collection there a couple of times in the 90s. My recollection was that it was very poorly displayed, just models roughly placed in cabinets and with little or no attempt at interpretation.
The Museum of Army Transport was a great place with lots of 'good stuff'. Unfortunately financial problems caused it to close in 2003 and the collections were dispersed. What happened to Sir Patrick's collection I know not. I have a memory that it went up for sale, but that one UK dealer said it really wasn't worth bidding for. A great pity.
