As far as the "rebated cyl"., all Army cylinders are rebated non-fluted, half fluted and full fluted. Otherwise, a .44 ball/ conical would be too big!

Sorry: I should have been more clear. I meant the usual rebated, smooth (non-fluted) cylinders like most have. Of course, such cylinders have a roll engraving of a naval battle between Texas and Mexican navies, as I recall. I've always been amused that a naval battle scene was on a revolver marketed to the Army.
