Yeah, those would be interesting also. There seems to be two sets of front knobs for the hero trap; there's the ones on the screen shot, and there's the ones on the hero trap in the reference section:
They're not the same at all. AJ actually sells the round ones in the shop. What about those? Are they correct?
And the tear drop knob on the other side? It's been identified, no? Is it different from one movie to the next? According to my research it's a Raytheon pointer knob, but I don't know the exact size or if it's skirted or not (I'm hesitating between the models MS91528-1P2B, 1K2B, 2P2B or 2K2B; 1 stands for .700 inches diameter, 2 stands for .900, P stands for no skirt, K stands for skirt) And what about the dial under the knob? Is it a simple painted washer, or what?
I think that's all the questions that I had about the trap knobs.
