I disagree and not that it matters, but I work in graphics too. Try this test... create a checkerboard image that's 2 pixels by 2 pixels and rotate it 45º. You'll be suprised at the random appearing blob you get. I know, you're saying that's only 2 pixels, right? Well, the reference used to measure the d-ring is the O/D of the graflex which is only about 100 pixels. So, 2 of 100 is already 2%. Resampling is inherently inprecise, that's why it's called resampling.

Um, yeah but thats why you do NOT begin to rotate a graphic until its at a higher resolution. You need to pump up the res first significantly, then if you rotate the checkerboard pattern you will get two diamonds on top of each other.
That is why its important to use a vector based program like Adobe Streamline when doing such things. Furthermore, once rotated, all of the measurements along the same line will still be in proportion to each other, remeber we are only measuring in the same direction for all 3 elements here.
BTW - your graflex body measuremnt keeps coming up small because you not accounting for the roundover on the outside edge of the flash. the light is only hitting the very end...if you look harder you'll see the roundover is shadowed slightly. Its only a difference of a few pixels at screen resolution. This is why a bit of extraplotaion has to come into play here to, it always does when working from photos...if you can scale the bracket to .75" and the d-ring come up as 1" OD, its a really good bet thats what they are since they are both even measurements and known sizes of available brackets of D-rings.
The explanation of the rings being of British measurement doesnt hold too much water either, there are international standards to consider...I can order D-ring from overseas that are listed in mm sizes, but they all correspond to US standard measurements.
OH, BTW that D-ring sales comment, give me a break dude, I argue in the pursuit of factual info here, not to make sales. It wouldn't do me much good to sell D-rings that turned out to be the wrong size, and have half the RPF mad at me now would it?
