Here we have a rather unusual wagon, I suspect with a bit of age to it.
The van body is cast, looks to be white metal which gives it a good amount of weight for a single van.
It would appear that at some point it had something affixed on the inside maybe a controller etc as the roof is removable.
It has some very interesting springing and axle boxes, the axle boxes are scale, but the spring is very over scale but extremely functional.
The van runs like a champ and is extremely free rolling.
The question is would you leave it as is, or change the springing?
