As you probably know, a Cape Gun was usually a side by side, one barrel being a shotgun, one being a rifle. Shotguns were usually 16 g is Europe, and 12 g for sales in the US. I know of no complete listing of the rifle calibers- .38-55 and .32-40 examples are common in the US. European guns usually use a European cartridge, such as the 9.3x72R. PS-amended the spelling of Pieper- search for Henri Pieper of Belgium, you will get more results.

All 1894 (aka M-94) guns made in calibers 30 WCF, 25-35, 32 Win Spl and other smokless calibers have Nickel Steel barrels. Guns made in calibers 32-40 and 38-55 may, or may not, have Nickel Steel barrels, depending primarily on when the barrels were made. Don Schimpff guncollector@att.net
