I know it isn’t a top priority but I am interested about that key fob on the belt.
when Peter Mosen shared his photos of the Screen used belt a few years back I noticed that the leather isn’t shaped like the main fob.
the leather pattern has a curved shape to it and everyone replicates that fob with a rectangular shape.
After seeing that pic back then I really notice that Aykroyd and Murray belts shares the design when looking though production photos.
I’ll try to get what photos I can, though it’ll likely be like the previous exhibition I attended, with everything displayed behind glass.
I’ll see if I can snag a photo, prop arrangement permitting.
Anyone able to shed some light on the use of 2 almost identical colored fabrics for the GB1 suit. I don’t think I’ve noticed this on any other suit, or have I just missed something well know for years, and why would they use almost identical fabric, if as the description says it was intentional?
Take those descriptions with a pinch of salt, some of the auction houses are notorious for using incorrect information.
A few suits have surfaced with the colour differences between parts.
It didn’t look that way back in 83, that’s just the result of certain peices aging differently.
It’s anyone’s guess why they used slightly different fabric on some of the suits as not all of them that have surfaced show this discolouration.
The 2 shades is actually really interesting. I’ve seen it for a long time (Venkman’s top right shoulder is very noticeable), but always thought it was due to an inconsistent dying or layering of fabric. Just an organic part of making the uniforms.
With the clarity here you can see how symmetrical and structured the pattern is, it’s obviously by design. But it was done so subtley you can barely tell in the film, so much that they didn’t even bother with it in GBII.
When you know to look for it it becomes more obvious;
In the book, Ghostbusters: The Ultimate Visual History, the original costume designer is said to have wanted the flightsuits to be a “taupe grey”, which is a color that borderlines grey and khaki. My guess is that they took the pockets and sleeves off of khaki army surplus and re-cut them with a grey fabric to create a new look for the film.
It’s possible that the material aged differently depending on what fabric the sleeves and pockets were cut from, but I’ve had snowsuits that aged so much that they went from a green to a grey, and the original color was still in the stitch, so the flightsuits original color of khaki is probably right.
I think the lighting conditions for the auction photo affected the colour grading a little, as reviewing the photographs I’d taken of it yesterday, the stunt belt appears closer to white/light grey rather than khaki (the suits, as is now becoming common knowledge, are about as Khaki as a modern Nomex, not a hint of grey in them - the likely product of the lighting equipment and the film stock).
Cole, here’s what I was able to get:
*Lower front section where the L-bracket is holding the cartridge in (hopefully this reveals what you were looking for, unfortunately the back of the Trap was angled away, and going too far to the left left it obscurred by Dan’s GB1 flightsuit):
*Area on the side where the “battery” box attaches to the handle plate:
*Bottom view of the trap where the bearing wheels bolt into:
*Bottom views of the pedal showing the feet
[*] Below the vector plate on the pedal where the tubing terminates (did you mean the pneumatic tubes, or the bellows? I’m afraid that I didn’t get a shot of the underside of the plate where the bellows connected, sorry. :()
*Any other interior shots of the cartridge if the trap is open (specifically the sides and bottom)
One of the Propstore staff enquired about whether the Trap could be removed for a closer look, but her request was turned down. The Trap was displayed in the middle of the case, which was packed in with two costume-adorned mannequins on each side, and only opened at the sides, meaning a lot of disassembly would’ve been required to bring it out. 
Unfortunately I wasn’t able to get much in the way of photo reference of the keyfob :(. The belt was curled up on a transparent shelf high up in the display case, preventing me from easily taking any overhead shots, and obscurring the underneath shots. Here’s the best I was able to achieve:
And regarding how the patches were attached:
Thanks for posting all these! It’s still hard, to my eyes, to see what color the belt is. In a lot of those shots they do look like a very light khaki/wheat color. I also notice there is a different material/color weaved in vertically that looks more khaki.
Not helping matters was that the cases had lights that threw out a warm yellowish glow.
Those things are notorious for looking completely different colours on camera depending on the lighting.
Even original light khaki m1936 belts and pouches have that issue.
Must be something with the way that shade absorbs and refracts the light , much like the khaki suits.
It seems almost impossible to accurately portray how they look to the naked eye because of it.
This is the same belt in natural light and incandescent light. 
Man, not just the belt… The radio looks so much darker when indoors.
Oh yeah, so it does.
Bloody lighting [emoji23]
Those photos are amazing and extremely helpful, thanks Kingpin!
I’m jealous you got to see all of that so closely.
Prop Store has everything up for auction on their site with a lot of pictures and video: https://propstore.com/movie/ghostbusters-all-items/
Thanks for the photos. This thread is really going to help when I start my suit this weekend.
Heading down to the IMAX to check this out today! Exciting!
Fingers crossed I’m able to snag something cool for the collection
Good luck Zed! Caveat emptor with the Ecto door logo (though I’m sure you already knew this) and Terror Dog head. 
Ha, yeah that door logo is pretty sketchy as well as the terror dog head. I’m looking solely at the Prop Store auction as the profiles pieces have too high of a starting bid to interest me.
I talked with Peter Mosen a few years ago about some of these items, and from what he told me the piece of aluminum on the back of the daughter board, to hold it on the belt, was one he riveted on back in the day, and if he recalled correctly original it was just a loop of leather on the back, so i guess it was like a key fob type thing,. don’t know if that is info anyone cares about, but I thought I’d throw it out there
