The Dinky Toys Dodge Farm Produce Truck was made from 1950 to 1964. It started life as Number 30n and was renumbered in 1954 to 343.
In simple terms you will find it in three variants: Yellow with a green back, green with a yellow back or red with a blue back. However it is not so simple as that. Within that colour range I have 12 variations listed in total. The first three are the colours listed above under number 30n which was available from 1950 to 1954 and sold from multiple trade packs of 6 pieces. Next we have the same three colour variants sold individually in dual numbered boxes with both 30n and 343 shown. The final variants are numbered 343, in the same three colour options with either mottled tinplate bases or gloss black tinplate bases.
