Just to clarify, H&A did make revolvers under its own name, but they also made guns for others and also made guns with trade names. The gun was patented by M&H, but M&H had no factory, so they had H&A make the guns for them. I don't have a large frame M&H (darn it) but have several M&H medium and small frame guns, as well as a couple of H&A revolvers. As one would expect from H&A, they are all very well made and top quality all the way, fully equal to S&W or any of the better makers of the time.

Merwin, Hulbert & Co. owned controlling interest in H&A & added on to the H&A factory so that the factory could specifically manufacture M,H&Co.'s Automatic Ejection Revolvers & they also hired the Craftsman to make them.
H&A insisted that they had a right to put their name on M,H&Co. revolvers. There was a rather larger row over it & the court ruled in favor of M,H&Co., so 1/2 of the Revolvers I've had contact w/ Don't have the H&A name on them.
M,H&Co. also owned controlling interest in Evans Repeating Rifle Co. & 4 or 5 other firearms manufacturers in that area.
Which is one of the main reasons that M,H&Co. became insolvent was because like Remington, they over invested at the wrong time counting on several large contracts to pay for all their expenditures.
So when the Russian Imperial Navy defaulted on the payment on their Million dollar order from Evans Repeating Rifle Co., M,H&Co. went under w/ H&A getting controlling interest in M,H&Co. W/ Evans meeting the same fate.
Unfortunately after H&A took over, there was a large fire that destroyed All of M,H&Co.'s records that were in H&A's possession. Which is the reason that there is so little out there on the Superbly Designed & manufactured series of Revolvers. The standard Bbl. lengths were 3, 5 & 7 inches & could be Special Ordered w/ multiple Interchangeable Bbl.'s. The Bbl. in the Pix has been whacked off w/ a Non-standard site silver soldered in place.
The majority of the M,H&Co. Automatic Ejection Revolvers I own are the Large frame 2nd & 3rd Model Frontiers & Pocket Armys. I corresponded by e-mail & phone w/ Art Phelps while he was writing his book. Though I was not comfortable w/ allowing him to Publish my collection of M,H&co. Revolvers in his book. My other research was found in Publications such as "Men at Arms" , etc. & Research Libraries. the
