Plastic wares? Yet another puzzle Billie. The metal model ships were indeed expensive at the time, my 1940 catalogue lists HMS Hood, Nelson, Rodney and carriers as being 3/9, most battleships 2/9, cruisers from 1/9 to 2/6, destroyers from 1/- to 1/3, the cheapest being MTB's at 4d. At these prices I had always thought them to be collectors or rich kids toys.
Thanks for your recollections.
