Stumbled upon this thread so thought I’d give it a go… all fantasy of course
Begin with an armoured car, a 'Roller' of WW1 pattern ex middle east. This would be a goer complete with original sand in every crack and cranny.
A Crossley Indian pattern armoured car – just for something different and also a goer. Comes with a basket and snake to frighten the curious.
Back to WW1:
A genuine wartime Holt caterpillar as used on the western front. It goes when IT feels like it which isn’t often at nearly 100 years of age.
Also, a Durkopp artillery tractor. Has never gone – will have to manufacture all the parts I need. Currently sunk up to its axles in the back yard. Everyone loves a wreck.
Three WW1 lorry chassis – kitted out for different purposes – lorry/troop transport/anti-aircraft
De Dion – lovely truck to drive.
Bussing – unique and a troop transport of huge proportions. Runs like a Swiss watch.
Tilling Stevens – a unique ‘high-voltage’ vehicle
From between the wars:
First a Thornycroft Hathi gun tractor – because they came to Australia and my grandfather was in charge of testing them for suitability to Australian conditions
Second a Scammell with tank transporter attached for carting around one of the really early British or German tanks. You always need something on the drawing board – even if it is fantasy.
