Brought up in another thread I thought I would go ahead and start another thread more focused on the GB1 Traps here’s some screen caps from the Blu-ray: ![image](http://cylandprops.com/trap/Trap1stBRcap.jpg) ![image](http://cylandprops.com/trap/Trap2ndBRcap.jpg) ![image](http://cylandprops.com/trap/Trap3rdBRcap.jpg) And the actual knobs: ![image](http://cylandprops.com/roundknobs.jpg) ![image](http://cylandprops.com/Gbtrapfrontknobsapol.jpg) I’m fairly certain that the two knobs are what was used. ---

I found similar square knobs online a few months ago but they didn’t seem right to me: ![image](http://www.gbfans.com/images/pb/jackdoud/Ghostbusters_IMG_9439.jpg) ---

Thankyou for the great photos and info Cyland! Now all I need is someone to sell me 2 square dials 😉 ---

From what I see in the pics I’m pretty sure these are the very same knobs. I think I can see the white stripe on the gb1 trap (2nd pic)… Am I right? ---

This pretty well clinches it. You can see the groove Click for biggie [![image](http://www.gbfans.com/images/pb/GB1Ref/th_snapshot20090616221534-1.jpg)](http://www.gbfans.com/images/pb/GB1Ref/?action=view¤t=snapshot20090616221534-1.jpg) ---

I’ll be posting a sales thread later today with some other items as well. I also believe I found the smaller round knobs on the face but do not have them in hand. ---

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](https://www.gbfans.com/shop/trap-tear-drop-knob) on [the other side](https://www.gbfans.com/wiki/publications/comics/ghostbusters-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. 😃 ---

Those front knobs are GB2 knobs Filandrius. The teardrop knob has been known for a long time. It’s supposed to be skirted but those are hard to come by. Most people just get the regular and add a skirt: ![image](https://discdn.gbfans.com/original/3X/1/a/1a23c4e7b5acb8a3be882ec76d6fd6352ee4b5f1.jpeg) It’s the knob on [the other side](https://www.gbfans.com/wiki/publications/comics/ghostbusters-the-other-side) that changes. ---

OK thanks, I wasn’t sure. So the trap in the reference question is a GB2 trap? I was sure that it was a hero trap from GB1 (all-metal, red rods…) For the [tear drop knob](https://www.gbfans.com/shop/trap-tear-drop-knob), is it a MS91528-1K2B or a MS91528-2K2B? 2K2B seems a bit big. ---

MS91528-1K2B it is then. Thanks for confirming this! 🙂 ---

I’m not sure it’s gloss black. After looking at the specs again, I can’t find a pointer with the angled skirt. What they call a skirt is just an extension off the bottom. ---

1K2B is flat black. Gloss black would be 1K2S. [http://ehcknobs.com/flash\_MS91528/MS\_point\_barB.html](http://ehcknobs.com/flash_MS91528/MS_point_barB.html) Exactly… The screen used knobs had the skirt. What most people call a “skirt” is actually a “dial”. And that’s what we can’t find. ---

I’m not convinced it’s a part of the knob. ---

Another thing to also consider is that those are 2 different traps shown in the trapping scene in gb1. A rolling one, then the one with the lights that “opens”. The one with lights that opens in that scene has the doors inset deeper into the body of the trap. And neither have the flat head screw in the front display box like the one in the reference section. If anything, the one in the reference section is probably the one from the [containment unit](https://www.gbfans.com/wiki/equipment/containment-unit) demo scene in the first movie. As for the actual subject as to what knobs are “accurate,” I’m still not completely sure myself. [Next page](https://forum.gbfans.com/t/trap-knobs/5991.md?page=2)
