Just finished cleaning a Win 1885 Low wall in 32 Long Colt? ( Just says 32 long) with a 30 inch barrel(has 1 under barrel) and a 2 leaf rear sight. Made in 1892. Is this rare? Isnt the 32 long a revolver round? Why would they chamber this long rifle in a revolver round? Will a 32-20 fire in this rifle? I can text photo if anyone would like to post. TY
