674: Coastguard Amphibious Missile Launch


The Coastguard Amphibious Missile Launch 674 was produced between 1976 or 1977 and 1978 depending on your source. It was derived, as was the 602 Armoured Command Car, from the never transmitted ‘The Investigators’ TV series produced by Gerry Anderson in 1973. Reg Hill designed the original prop. The pilot programme is available on DVD.

The launch came equipped with a rocket launcher, activated by twisting the searchlight around, and three rockets, two of which could be stored behind the pilots seat. The missiles were the same as used on the 691 Alvis Striker vehicle.

Underneath the red seats and out of sight was the giveaway Investigator Boat marking.

The design was based on Reg Hill’s (Gerry Anderson Productions) spy boat for John and Julie, the marionette stars of The Investigator.

As with 602 it seems that Dinky were trying to get ahead of production of the TV series to ensure their models would be ready as soon as the TV programme aired which of course never happened so after waiting for a time they were re-invented as different concepts.

The Dinky model had twin rocket engines, a swivelling rocket launcher at the front which came with 3 missiles and a customs officer in the driving seat.


The prop for the TV series was yellow and white with a red mast and chromed engines and did not appear to have any weapons. Dinky changed the colours to blue and white with red seats, kept the mast and engines but these were now blue and added a missile launcher.

There is a turquoise-green engine variant and there were colour shade differences to the most common blue engine model.

There are also a number of Code 3 variants available which show how the model may have turned out had the TV series been commissioned.
