Much to my surprise I found oldish 320 Long smokeless ammo at a gun show near Paris- yes, there are gun shows in Europe. It cost me a bit over a euro ($1.25)

a round but I did get 25 rounds of live ammo with lead bullets. It's a tad shorter, about 1/8, than the 32 Long Colt, chambers fine with both my no 2 Ballard and my Marlin model 92. I shot them all, now I've got some more brass for reloading. So for any collector East of Newfoundland, there's hope...Look for 320 ammo.
