I think it's a great idea and there's a lot more to figure out about Merwins than their enormously more documented and discussed better known competitors.
While there are Hopkins & Allen topbreak revolvers that look nearly identical to period Smiths, Iver Johnsons, Harrington & Richardson, and others, the Merwin's ejection system of sliding forward isn't a top-break, a "forward-slide" (boy is that awkward) that you only see elsewhere in the French-designed Galant-Somerville revolvers 1868-1870 forward that use a long lever hinged underneath the barrel to slide the cylinder forward so that only the spent (shortened) cartridges fall out.
Learning from others is the only way we can progress on the many mysteries of Merwins, just like many of the other 19th century innovative guns that have far more mysteries than Winchesters, Colts, Smith, etc. that have been talked to death 40 years ago (that's when I started reading about them and the discussion really hasn't changed much on the old models.)
