I've got one of the NAA "Companion" C&B revolvers. Mine is the ".22LR" frame, with 1-1/8" barrel.
I think they are substanially similar revolvers, minus the "loading lever." I'm not sure, but I expect the "loading lever" on the C&B Earl is just for looks, and you actually load the cylinder out of the gun with the included press, just like their other C&B revolvers.
My Companion is lots of fun, in a goofing-off sort of way. Like all of the NAA minis that I've shot, it's a quality piece.
