"Aussie Pete," from Australia of course, told me that he had seen a number of Holland & Holland double rifles, with so-called hidden third fastener, stretched at the hook, but that he never saw same condition from a Rigby with rising bite third fastener, and, I believe the same can be said of a good British double with the Greener crossbolt, if well fitted and tight as it should be. Anyone seen any similar such damage done to a double, and, if so, please describe what damage took place and what type third fastener it had.
