As near as I can tell this is Kodak 100 Ektachrome Professional Color reversal 4x5 film. I used the notches to determine it is Kodak and not Fuji. I only have a few exposures made with it but it was some nice film indeed. I had this processed in a lab.
Taken in Tucson Az circa 1989. Scanned...
The photo came out well but it could have been slightly wider. My main comment is
that they couldn't have made the girder system any more complicated. I suspect they
did it for looks I'm not getting it. :-)
I have the Crane-M and once you turn the power off they go very loose and unpredictable as gravity takes over and you have 3 axis that are uncontrolled. I wouldn't worry about it unless it behaves funny with power on.
