Yesterday I found two examples that are both ok I hope. I believe this is a 4th and 3rd Class.
The 4th class is much thicker than the other, the hanger is much more sturdy and the balls on the tips rounder and thicker.
The third class is thinner, lighter and the metal "diamonds" inbetween the cross arms are not as detailed. I'm not so sure about this one although it looks a lot like the previous manufacture type that Risk showed the 4th class of.
Opinions appreciated.
3rd Class, sorry, reverse first.
