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.

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.
