Ignore my previous post. Now I know why your quest is so difficut. I was just thinking double rod cylinder, but most double rod pistons (like steering cylinders) move in a straight line (i.e. when one side retracts, the other side extends). You need a cylinder where both sides retract at once or both sides extend at once. The line sending hydraulic fluid to the two ends is the tell. Maybe a hydraulic shop could give you the nomenclature?

My skid loader does the same job with a regular single acting cylinder. As long as the pins had a stop so it had to pull both pins vs pulling one twice as far there’s no reason it wouldn’t work.

Bob-Tach and the like ones I've seen are all single cylinders with the base of the cylinder pinned onto one quick attach arm and the ram pinned onto the other quick attach arm. because of the 1/4" cover on my coupler, it appears to me that the cylinder was fixed center with two double-acting rams. Anyway, way less expensive to use a single cylinder. To do so, I drill mounting holes in the ears of your quick attach levers then measure when wide open and also measure when all the way closed and use a find it tool to select the right sized double-acting hydraulic cylinder.

I left a message for the parts guy Bill, at Rockland asking if a newer cylinder can be used in my Coupler. What I can say is that the 3" wide pins are threaded for 1' x 8 thread pitch, so super common size that would allow me to thread bolts into the dowel pins that hold the Coupler onto attachments, and then puzzle out how best to pin those bolts to a cylinder or ram. If I must, I can make a single-cylinder work leaving the tough cover off so the hoses don't get damaged from the cylinder moving around.

Thank you for looking! Sadly, all of those are steering rams and I've ruled them out after confirming with Surplus that they didn't have anything like what I'm looking for.
Edit: I just saw your second post. Good graphical explanation. Smile.

Super cool! Bill the parts guy from Rockland Manufacturing called back and took my bucket and coupler part numbers down, explaining that Rockland does have those records in a different location as old hard copies. Bill explained that it would take him a day or two to find the records but he'll email me the parts book and part numbers to order from one of their dealers.
This is a way better result than when I called Rockland last year asking about the same thing and was told everybody who knows anything about that has retired.

While we're waiting, how about telling us about your relationship with that Hough?

Once I bought new front tires last spring, my machine hit money pit status but the whole process of fixing it up is more or less being documented in an ongoing YouTube series that is best watched on your big screen TV.
Originally the machine was doing municipal work in the southern part of Minnesota and was then sold to a farmer up in my neck of the woods. That guy passed and willed it to a neighbor farmer who neglected it but only put on about 130 hours over the next decade. The batteries has failed somewhere around 2018 and so there is sat. That farmer inherited a farm down in Iowa and liquidated his assets up here which is how I came to purchase the machine. Now the machine itself is getting better and better as I fix stuff on it. This season I hope to sort out the wiring (lights and gauges), I'm removing the existing Racor water separator and adding a heated Racor water separator for cold weather running, and I'm going to service the transmission. It all depends on how busy my job gets.
Subsequently, I've run into a guy doing commercial snow removal with the same model and he wants to buy more of them and I can see why: compared to a modern 200hp loader, these things weigh the same, flow the same hydraulically, lift the same without the 200K price tag.
For the interested, here is the first video of the series.
