Question 1860 Naval Engagement Scene

[Long Johns Wolf]

Howdy to the campfire: if memory serves the Colt 1851 & 1961 Navy and the 1860 Army have the same naval engagement scene roll-engraved onto the cylinder. But is it identical in all details?
I found the marking Engraved by W.L. Ormsby New York on 2nd gen Navies (1851 + 1861) but have problems discovering it between the scene on my 2nd gen Armies with rebated cylinder. Now here are my questions.
Is this reference to Ormsby regularly on the Colt Armies of 1st, 2nd and 3rd gerneration with rebated cylinder? 
Is this reference to Ormsby also on Uberti Army 1860 replicas with rebated cylinder, particularly on those made during the 1960s?
I can tell you it is not on the Belgian Colts with the Ormsby-type naval scene.
Thanks for your help.

The Armies had the same naval scene as the Navies. There was an article in Man at Arms journal last year or so discussing the merits of detecting frauds by visually inspecting the roll engaving on original 1st Gen. revolvers I believe. However, an alternative theory was that dies broke, wore out, etc., and that this caused variations as well as more than one roll engraving press was used at the factory.

Had the opportunity to study pics of cylinders of some 10 1st gen Armies made between 1862 and 1870. None had the reference to Ormsby. So let's assume 1st gen Armies had no reference to the Ormsby enbraving.
But what about the Uberti 1860 Army C&B pistols? Do they have the Ormsby marking?
I noted the marking on the cylinder of an Uberti RM Army, however.

All my cylinders, on guns and spares, by Uberti, have the Ormsby reference, 51, 60 and 61.   My 2nd gen Army is fluted, no help.  My 3rd gen Army has the Ormsby stamping, as has my 2nd gen Navy.  The only cylinders I have without the Ormsby reference are an 1860 cylinder I believe made by ASM, it allso has no safety pins, and the cylinder on an original 1861, which is a replacement

James Serven's book states the 1851 has the Ormsby stamped below the serial number on the cylinder, and describes the 1860 Army as having the same Naval battle scene, but does not specifically mention the Ormsby reference.
