I think it is 100% sure thing that the base gun is the ANH hero for both the "Dagobah" style castings and the Merr-Sonns. The serial on the upper is a match, the c/c/u mark below it at the funny angle , the hump behind the bolt-stop. Merr-Sonns were made for ANH and looks like they were just blank guns, all the greeblies are added on top (except maybe the long greeblie between the tomtit antennas). Could be that the ESB ones were also just blank casings left from ANH and they added the greeblies for ESB, or took one casting, decorated it with greeblies and then made a mold from it.
I wonder why the triggers are looking so different on these two
I was able to replicate this difference to some extend on my builds, but that's just because I tried to match each individual build to the references, otherwise the triggers were going to look pretty much the same on all of them.
