A typical Cold war era Universal towing arm seen on many RAF Bases during the Cold war. This set comes with parts to make 3 different lengths of arm & has 2 types of leg, with one being slightly thicker & having larger wheels.
Separate arts are provided to print & assemble yourself, as well as the 3 types as assembled models.
The models are all produced in 1/1 real world scale in metric. For most slicer software, Metres will be read as MM & will need to be scaled accordingly.
The shortest type is overall 4.47m long in real world measurements.
