Well, after months of looking here and there in vain, I found a Marlin 1894C carbine. Ellwood Epps in Ontario. I normally wouldn't buy a gun sight unseen any more, after getting some so-so stuff over the net. But this is brand new, and I've played with it's big brothers and loved them. This one is 357 mag. The cowboy action guys have bought them all, so it's rare now, until Marlin sends more. I can't wait to get my grubby paws on it.
