In all seriousness, I would ask on the ASSRA Forum. There is a pretty active population of 200yd, hind legs shooters (Schuetzen) (sp?), guys around the Calgary/mid Alberta area that sometimes post their accomplishments on that site. My two guesses are that if anyone is going to have or know who has, what you are looking for, it is liable to be those lot, and my second guess is that you should expect it to cost you a bunch, to get something worth using!
Last decent (and reasonably priced) Win High Wall action I saw and regret passing on, was at a Moose Jaw gun show in the late 1990's, for $400. Gone by the time I had my regrets... LOL! Saw an old fella at an Edmonton show early 2000's, with a Stevens 44 1/2 switch barrel rig that he wanted $850 for, had a rimfire barrel, a Hornet barrel, and a (IIRC)32-20 barrel with. Been to a lot of shows and seen either "Original Patina" guns that should still have had the rope that was used to drag it the full length of the Oregon trail (ie:junk!) or that had been done over by some slob with a 10 hp buffer, until all the pits and most of the markings were melted off, before they were hot blued (also junk).
