Still available here too. I have a couple of used knee sets in the storage (a few find they peel off eventually despite following prep cleaning) and there is a new old stock set on sale here in Oz that has been there for years.
He is selling them for half the old stock price of Au$66.55. They were about double that when last sold at dealers.
Postage to me is about Au$15 and probably Au$65 for him to post overseas if he was willing. He was a dealer at some stage and has another Triumph leather jacket and a few other bits.
