Richard had posted a couple of images of these Colts in a thread on pairs (search for: "Post your Pairs" in the Hand Ejectors 1896-1961 forum, It is a thread worth revisiting).
The images you've posted here Richard really show off the magic of the engraving. The artful combination of the restrained gold line inlay, and the frame case colour, with the engraving is just remarkable.
With both revolvers in their case, and the "warmer" lighting that gives, it near makes them light up and sing. Great images.
I've seen a lot of fine firearms, mostly English shotguns and double rifles, but not such a remarkable visual combination as this. It is simply breathtaking.
