Sorry Tholt, I wasn't clear. The perennial question to which I referred, above, is not about Rawson gear in particular, it is about almost every make of gear that appears for sale in a cluster ( or IME not in a cluster, even ). The question being, "Why are there so many (put brand here) (put unit here) for sale recently?"
The other two questions you mention are, of course, perennial too.
