That's the spirit, Steve! Without people willing to tackle the impossible, progress would be lethargic.
I run into a lot of negativity at work. People are quick to give reasons why something won't work but are very reluctant to try it out or suggest methods which will work. I would rather try something and know for sure if it works or not rather than speculate.
I was most impressed with Polaroid pioneer Edwin Land when reading his biography. He didn't like finding a solution to a problem quickly as although that gave him an answer, it didn't tell him what the variables in the process were. he preferred to do lots of trial and error. A process he called success through failure.
If the word SPEED does not appear, but just the words Super Graphic, it never came with the wind-up chrome 1/1000 shutter or the rodenstock lens as standard. The camera with Super SPEED Graphic on the door was the upgrade, in lens only I believe. I struggled with that for some time.
I had only one Super SPEED, and the 1000 shutter. It was a miserable shutter, while the rodenstock lens was good. Shutter speeds were all over the place at higher speeds. (Yeah Right! you get used to it and compensate)
All the others I owned were Supers and I had not nearly the problems shutter and lens wise.
So all those Supers that you see on eBay... look at the door. If you see a Super SPEED with a lens shutter other than the chrome ring hanging out in front, it's already been swapped out.
If you see a Super without the SPEED on the door, and it has the chrome ring, it's likely been "upgraded" by a user to the rather wonky 1000 shutter lens. (WHY? It never shot 1/1000 on it's best day. According to Fred Lustig, the components inside the 1/1000 shutter were too large and heavy to reach the top speed)
I spent so much time learning and wrestling with that useless information, I just had to say something.
disclosure: I expect to be corrected on some of this. However, I do not know if the marketing/availability of the Super vs the Super SPEED overlapped, or whether you could still order a Super, with the upgraded lens. My references here are merely from personal experience.
One more little tidbit... Graflex sold the Super to Toyo and Toyo place their own brand in front of the Super and it became the Toyo Super Graphic, on the name badge on the door... predecessor to the Toyo metal field cameras. There is a Toyo Super Graphic on eBay at this time at $1495 Buy It Now.
