I have seen a couple of the stainless barrel trials rifles, and have quite a few pics of one. Yes, they were standard profile barrels, but having seen plenty of other "stuff" that was undeniable but still almost unbelievable, I don,t often use the word "never" either. Looking forward to some pics of the shiny areas and the markings if possible!
It would be a shame actually if one of the stainless trials rifles were striped out to put the tube in a HT, one of only a dozen or so and infinitely more valuable than a HT.
