'terms get changed or applied incorrectly'. When he says ' "Realist 
Format" means a specific thing' I suppose he means the 41x101 outer 
dimensions of the mount and maybe all three mount aperture formats? Or 
also camera aperture size? Or should 'format' be understood in its 
general sense, so including camera design (35 mm lenses, 70 mm lens 
separation, 7 feet window). You see, 'specific' is not necessarily 
specific to all. And indeed, how to call the family of 41x101 mounts? 
>From the 1950s on there were also Belplasca mounts 41x101, aperture 
format 23x28. An objection to Donald's proposal could be that 'Rochwite 
mount' could *also* be understood as meaning inner as well as outer 
dimensions, so not including the 23x28 or other non-5P apertures.<<

I support the need for a term to accurately refer to the 41x101 mount. 
When we used the phrase "Realist-format mount (up to 7p)" in a recent 
PSA exhibition, I had a 5 star (read *very* experienced) stereographer 
contact me to see if they could still enter since they don't shoot with 
a Realist camera. It was obvious that this term was not only new to this 
person, but confusing because of the "Realist" part of the description. 
It was new and confusing to me, too. If we had one term for the 41x101 
size mount, then we could put the opening after it, and the brand (if 
necessary) after that, i.e. [new name]-7p (RBT) or [new name]-23x28 
(Belplasca), etc. The term "Realist" is misleading as it is tied too 
much to the actual brand name of the camera that usually has only 5p 
images. JMHO.

>>Abram Klooswyk: As a personal note, I considered it an honour to sit 
next to Seton at the closing dinner of the I.S.U. congress in 
Arlington/Washington, 1985.<<

I also had the honor to meet this great man in Arizona in 1996, shake 
his hand and get his autograph on my PSA conference program.
