... an edition which fbb (then aged 14) remembers buying!
The truck sold at five shilling and nine pence (29p) empty and six shillings and eleven pence (35p) with brick load added. That would be about £5 and £7 now. fbb never bought one because it was a bit pricey and, being a bit of a model railway snob, he couldn't think why a huge brick wagon would appear on his small country branch line layout.
And if you wanted one of these today, fbb's local model shop has a pre-owned couple at £8.50 each.
