Meh, I've written like 3 pages worth of posts on this going back and forth with ORDB so you can go back and read that if you want my opinion for what it's worth (not much). Some people are SURE there are multiple mold pieces, some people are SURE there are not. I have no idea which way it is, although I will reiterate that I believe Innova has some control over it (at least now they do, although probably not in the past).
I think they 100% have control over it. They can(and have) been molding up destroyers to fit what people want them to be(ex.- during the bomber run of AJs, ppl wanted a more OS destroyer. Then when we got the more OS destroyer in the form o mcbeth destroyers, people waned a bomber run again, so they made the current embossed run).
just IMHO, YMMV
