I found another 1/35 scale truck kit of an earlier version of the Opel Blitz, a bit more thirties than forties looking. It is in fact a gas producer. The long vertical tank shape on the right hand side was used to heat either coal or wood chips and the gas given off was collected in a pipe and directed round to the front of the vehicle. Here it passed through a radiator which cooled it then it was stored in a large tank fitted crossways to the front of the truck. The gas was then fed into a carburettor to power the engine. It produced about 40% of the power that petrol would apparently. It could run using petrol as well in a conventional way if required.
This time I managed to get it to fit over a Con-Cor switcher chassis. It is very similar to the Athearn but with a can motor. It came out of a loco I’ve had for years but never really liked because of its awful over scale hand rails. This time to get it to fit meant removing a flywheel and drive shaft to fit under the cab and bonnet. The body is held in place by two self tappers each side that press against the sides of the motor.
A large tarpaulin covered box in the back hides the motor and drive mechanism. I sprayed it with grey car primer then picked out the wings and radiator outer cover in black. I washed the whole body with a mix of black ink and grey acrylics to tone everything down a bit. The driver is a modified military figure.
I then added ropes and chains and a few oddments in the back to make it look more interesting and give it a bit more character.
Originally it was fitted with a Kadee coupler at the front but because the rail truck is rather longer than the other Opel Blitz it swings out too much and was a menace in the yard. Now the front sports a wooden buffer only to protect the front of the truck.
I fitted a kd coupler to the rear instead and added a petrol tank under the front near side wing. It is as far from the heat source as I can get it. Now the vehicle is started on petrol then when warm changed over to gas.
The first two photos were taken on my test track. The others on the model itself at a later date.
