This is the Strathearn Cyclone weight designated as P40 and first issued and introduced in May of 1978. Official description is "multicoloured ribbons swirling round opposing ribbons of colour". The outer swirl of colors are the same as used in the P36 Whirlwind of white, orange, yellow and blue. At this time I have no idea who made these or how many might have been produced but when and if I find out any more information I will post it here. The photos below are different views of the same weight.
