OK, I checked out the auction, but I see that it ended back on the 6th...
The picture link in the auction page is now dead.
I've bought from that dealer before, and I think he's a good one. Often he has Stadden castings, I've gotten some of the ones you see in some of my threads, from him.
I just went to my primary hardcopy resources, my editions of Richard O'Brien's "Collecting Toy Soldiers". I was astonished to find no mention of Marlborough in any of the editions, whether in the 4th, "Collecting Foreign-Made Toy Soldiers", or in the Newer Maker section of the first 2 editions. There's also no mention in the 3rd edition, "Collecting American-Made Toy Soldiers", but then, it's about American-made toy soldiers.
I next went to Bruun's "Toy Soldiers Indentification and Price Guide", and there I found an article on Marlborough. And it's clear now why they didn't make it into O'Brien's book. When he published, Frank and Jan Scroby, who ran Marlborough, were still busy trading as Blenheim. Bruun notes that the Scrobys produced figures from the Victorian era, both from Great Britain and from the Empire, featuring the Durbar sets, as you are probably all aware. He also includes a picture of a set called "Early American Heroes". There's no mention of the British army from the early 18th century.
We do all know and agree that Marlborough figures were marked "MMM", for "Marlborough Military Models", and if these figures have that mark, it weighs very heavily for having been produced by the Scrobys. But I still wonder if their origin, either as masters, or as castings, lies with Gammage, because of their similarity to the Rose figures.
Either way, they are very nice figures and a coup for your collection, John!
I'm not giving up, but I think this may take some more research. And yes, I still need to take pictures of my Tabony figures and put them up, for comparison
Prost!
