I have a third model, large frame, double action Merwin Hulbert. It is missing the loading gate. I also have a second model, large frame, single action Merwin Hulbert. They are both in 44-40. I can use the loading gate shape on the single action as a guide to make one for the double action. However, there was a change in how they were attached. Does anyone have a third model that they are willing to take part and show me the back side of the loading gate so that I can replicate the attachment method that was used at the factory? The second model has a detent ball and a trigger screw that holds in the loading gate. Neither of those are possibilities on the third model.

Most guys aren't all that interested in disassembling their revolvers for fear of losing/breaking parts, and spare parts reside in other folks' guns, who are quite proud of them.
If you're still looking for an answer for this question - look at 'Gunsmithing the Guns of the Old West' by Dave Chicoine.
Scouts Out!

Sorry I can't help you as much as I'd like.
Here are some photos of the relevant parts of a 3d model double action (skull crusher). The gate is externally similar to the single action gates, but the backside is different. You'll also see the additional tiny screw above the thumb screw. Unfortunately, the head of my tiny screw has split in half, so I am currently unable to remove it.
From what I can see, on the double action, the thumb screw threads into a small flat spring located in a groove on the underside of the loading gate. That spring applies pressure to the frame to retard the gate movement. The small screw extends through the gate at the opposite end of the flat spring and protrudes into the groove in the frame. It doesn't seem to touch the end of the flat spring or bottom out in the groove, but in a quick look I can't see what it does.
I know this won't give you all you need, but perhaps it will help at least a little.

It's been a month since you've been here so I'm quoting you to hopefully get your attention to some replies.
And as to Chicoine's book, the expanded 2nd edition that I have only covers the single action M-H. Good luck.

Wish he'd come back. Sounds like an interesting project.

Some folks seem to sign up on a forum for “one thing”
And then disappear.
Sort of an internet “stranger just passing through, asking about that one eyed one armed six fingered man….
