This is an M8 Greyhound 6×6 Light Armoured Vehicle (or something close to it, as builder Robson M doesn’t specify!), built by Ford in the 1940s for Allied troops during World War 2.
The British, who like naming their military hardware after animals and the weather, gave it the ‘greyhound’ name, as it could sustain 55mph on reasonable roads, which was very quick for the time. And – at least in this one’s case – it was grey.
Much like a real greyhound though, the M8 wasn’t particularly well armoured, especially underneath, and nor was it very good off-road, despite being a 6×6. However it was useful enough that 8,500 were made, and – again like its namesake dog – many found new homes after being retired from their first military owner, with some M8s still in service around the world as late as the 2000s!
This neat Town scale version captures the M8 Greyhound rather well, with Robson using a few custom decals and a custom machine gun mounted on top to add to the model’s realism. There’s more of Robson’s build to see at his photostream – click the link to make a visit to the dog track.
