Well, that's what all the later ones look like, right on that brochure. Every one of those is a highly corrected plasmat. But one thing you have to realize about the specs in that, is that they're given with respect to graphics applications, apparently due to the Claron graphics trade lineage, and that those standards in terms of angle of view and circle of coverage, are far more stringent than what is acceptable for general photography. Yet also get 1:1 as well as infinity coverage specs, at f/22. But 8X10 photography generally uses smaller stops anyway.
You have to be careful about 270's. There were two versions of them, and only one of them was corrected for both close range clear out to infinity.
355 in a smaller shutter? Never heard of that. It must be a private modification. The Fuji 360/10 A series lens is very similar, except multicoated and in a no. 1 Copal shutter standard - ample 8x10 coverage, but dicey for 11X14. It has always been my opinion that the significantly greater coverage of the 355GC is probably due to its avoidance of mechanical vignetting due to its larger no. 3 shutter. But what is the image quality in those nether regions of the image circle? It's hard to say, because people who use that degree of coverage seem to all be contact printers, who don't need high resolution for the print to look great.
