It was mentioned somewhere on this site, or perhaps as a comment on youtube.com, that it seemed that whenever the Shrine of the Silver Monkey was shown while Olmec announced the location of the artifact, the Silver Monkey was assembled. While I find that this is true in most cases, I wanted to just mention that "Thornwood Gavel of Judge Roy Bean" is an exception to that rule.
As you can see from the image above, courtesy video posted on youtube.com by ChargerTheWolf, the Silver Monkey was not assembled when Olmec revealed the Gavel's location.
