This is a Dinky 359, Eagle Transporter from the TV series Space 1999. This was a very popular model for Dinky in the seventies. It was also produced in metallic blue, the colours are a slightly strange choice as in the TV series the Eagle spacecraft were always white. A cargo version of this model was also produced, this carried a magnetic hoist and four ‘radioactive barrels’.
The top four pictures are of the later more colourful version of the blister packaging, the model also came in boxed or standard blue / black blister packaging, as shown in the bottom pictures. The model was produced between 1975 and 1981.
