(sorry about the poor quality photos)The drums appear to be 8". The studs have been bent as it was sat on wrong wheels, so cant identify the pcd but appears to be approx 3.8" but obviously more likely to be 3.75" 4" 100cm etc [frame]
Other distinguishing feature are two large 'rings' at approx 45degrees to the axle line. And there are some other metal brackets at the end, although obviously these could be later additions.[frame]
