A few years ago I was able to get a hold of an original in 44.40 for an affordable price, for what they are, with found money I had.......turns out it had mismatching numbers (whatever, I don't care), and from what I've read, this is most likely assembled in the 1890s from parts left overs (again I don't care)..........
That being said, comparing it to the Colt Peacemaker, and the S&W Schofield, it does seem over engineered for what it is, and it's time. On the surface, Colt seems minimalisc in design, S&W has more bulk, but a quick top break to dump spent shells, and the MH has sliding loading gates, frame twisting for dumping spent shells, all kinds of nook and crannies for fouling to get into......ugh.
Unique design? Hells yeah! .....but seemingly over engineered.
I'm not a firearm historian specialist, but how it all seems to me.
