Thanks! I think it’s important to step back and try and look at these things from a practical, logical viewpoint, rather than tossing out outlandish theories. That being said, it’s also good to examine things from different angles, and ask challenging questions (shooting down outlandish theories can lead to more plausible ones), but we need to stay tethered to reality, rather than going off into the stratosphere with conspiracy theories.
These were props thrown together from junk for a movie everyone thought would most likely fail. I don’t think anyone in their right mind would have wasted the time, money, or energy swapping out parts like the bunny ears or beer tab rivets UNLESS there was a legitimate reason to do so, like serious rust or damage.
Again, I stand by my assertion that, if anything, only the three major components may have been swapped around, and then only because they wanted to mix and match the least-blemished parts to create the best-looking prop, or because they idly mixed and matched parts while examining the flashguns without knowing there were manufacturing variants.
C’mon, guys, there are MISMATCHED RIVETS in-between the grips (probably to hold an inner core in place which would help anchor the d-ring bracket). If they didn’t care about how that looked, they certainly wouldn’t bother to swap out something like the contact pins or the beer tab rivet.
The simplest answer is usually the correct one. The flashguns were likely used as-is, with the other found parts stuck on. I think any mix of Folmer vs. Inc. parts we may be seeing is because of manufacturing variants, or because the prop crew stuck Upper A with Clamp B with Lower C without realizing it.
And as for the original photographers swapping out parts...guys, I don’t think the press was having the flashgun equivalent of 70s key parties, with everyone throwing their flashes in a pile and mixing ‘em up. Again, the simplest answer is that the flashguns were used as found, and that the parts were assembled just as as they came from the Folmer Graflex Corp. and/or Graflex, Inc.
