I would tend to think something was wrong with the Anaconda. The broken spear is a part of the Rampant Colt logo. This is from a Model 1911 manufactured in 1913, and I would find it hard to believe that Colt would change the logo that has represented them as long as that one has.
The Colt logo may have been stamped in steel, but it wasn't carved in stone.
In other words, the Colt logo has changed subtly many times over the years with the Pony getting fatter then thinner again, the spears moving around at different angles, and the position moving all over the side plate of revolvers, sometimes to prevent being covered by Target grips, often for no known reason.
Unlike other logos like S&W or Ford, the Colt has changed over the years, but it's still the Colt logo.
In Joe Poyer's excellent book on the 1911/1911A1 he discuses and shows 13 variations used at different times on that model alone. Good source for all markings on the 1911/1911A1 and commercial variations.
Interesting....I took a look at the guns currently laying on my workbench...a New Service, a 1877, a MK V Lawman, a King Cobra, and a Woodsman, and no two are exactly the same, but all have the two pieces of the "broken lance" in the logo.
Any marking that was applied by a die changed over the years as new dies were made. I don't think the variations in the Rampant Colt reflect as much an intentional change as it does just a difference in the dies from one maker to another. Over the almost four wartime years of Colt 1911A1 production the Rampant Colt shows variations in the die. As the old dies broke they were replaced by new ones, and it appears that Colt made no conscious effort to exactly replicate the broken die.
