I'm pretty sure that whoever has assembled this has made a mistake with the front end. It would be impossible to ride with forks at that angle.
If you turn round the front forks so that this piece

is flush with this piece
Then turn round the handlebars and lights and mudguard so that they're the same as present, then it more or less makes sense.
Looking closely at the engine, it appears to be an air-cooled two-stroke V-twin. The carburettor is in a box under the seat. This would have to be really bad design! I'd guess this puts the motorcycle in the 1920s. The seat seems to match that.
Out of curiosity, how big is this model? What's the other side look like? There's no exhaust pipes on this side.
