So after sitting with my goggles for a while, I decided to make some modifications to move them closer to screen accurate. A while back, I drilled small holes into the frames where the original night vision goggles had screws. That stressed me out a bit but the ABS drills really well and it was easy once I had the spaces all measured out. After a signiciant passage of time, I got ahold of some Mack's Factory dry rub transfers, which were really good. One small caveat to that, though, is I miss when the MF dry rubs were all inclusive. The first set I got back in 2018-19 had enough for like, two proton packs (including Clippard 3814-1 tubing transfer), a trap, and goggles. Now, the sets are pretty limited, but oh well.
Then I heavily modified the straps. After poking around on Egon's 1984 Workbench, I got a little more info on straps. I'm not convinced my straps are accurate but they work best for me. I tried Nylon straps but the knot didn't stay and they ended up too loose, so I went back to elastic strap. The big step was drilling out the included snap on the top of the housing to make way for the d-ring, but after some deep soul searching I decided, "screw it. What's the worst that happens?" and went ahead. I think they look great.
Finally, I recognize the power knob is incorrect but I can't find a reliable source for what was actually there. I know a lot of people think it was a thumb screw but even that, there is disagreement on. If anyone knows a good solution, please share a link. As of right now, I'm calling these good until I can find a solid piece of reference for the knob.
