A goodly many years ago, when I was in college, I had the duty of returning the film club's borrowed reel to the New York City rental company. (Told you it was a long while ago.) There was a gun dealer near the company and I dropped in. They had a Holland Royal rifle in 465 in as new condition. Cased in oak and leather. Complete with a set of dies. And 60 empty brass cases. All for the price of $750. Of course, that was half a year's tuition. And, those were the years when 465 ammo was totally unobtainable. So, I passed. (By the way, a new rifle would have been about GBP 1000.) I could have traded it for a Bentley now.
