rotating a pic wont distort it at all especially at a higher resolution.

This is incorrect. Rotating an image (or any form of resampling) works by reinterpreting each pixel by comparing it to the pixels around it. In addition, this is not a high res image! Using the O/D of the graflex as a basis of measurment is only about 100 pixels. So, if one measurment is off by 1 pixel of 100, that's 1%. If you're trying to be accurate, don't resample the image. Make it a negative for an additional view.

If you take the pic I posted with the red outlines, copy it, and open it in photoshop, you can measure the elements there with the lasso, make sure the res on the pic is 72 dpi and you should see everything just about falls into place.

I did. Please reread my posts. I find it very hard to believe you've measured the pic and came up with 25.4mm. Measured at 94.7º I come up with 1.393 for the O/D of the Graflex which is 38mm in diameter. I also get 1.003 for the O/D of the d-ring, .744 for the hinge width, and 1.289 for the ridge I/D. These calculate to about 27.3mm, 20.3mm, and 35.1mm (you'll note 35.1mm is EXTREMELY close).
I don't know how you've determined the bottom half is pushed in by 1/16" without any good 'length' reference in the pic. Especially since it's angled away. Do you realize you're talking about an accuracy of 1.5%. If you can determine this, then why do our d-ring numbers differ by over 6% with good reference points?
In short, please most your measurments.

Also dont forget that D-rings come in standard sized, most commonly 3/4" 1" 1.5" and such...to have a d-ring that is an odd size like 1 1/32" would be kind of odd, rare and likely impossible

Considering it was made in England (right?), it may be metric or it may be a custom size part taken off something else.
EDIT: No offense intended.
EDIT: To be clear, the numbers 1.393, 1.003, .744, and 1.289 are the numbers directly off the unscaled picture. Scaled and in millimeters, they're 38mm, 27.3mm, 20.3mm, and 35.1mm.
