My Home-brew Sons of Vulkan used to be a Salamander successor chapter but they had Power Armour issues (#1) and then got lost in the warp. (#2)
#1. GW changed there paint range. Shining Gold turned into Gahenna's Gold, which was a completely different shade and any new painted models looked completely different, tut.
#2. By lost in the warp I mean sold on e-bay.
