I am going to take a look at a few scratch-n-dent stereoscopes and I was thinking about taking some printed calibration / test page with me.
I've spent a bit of time searching but don't find anything obviously made for this freely available.
I am guessing something like a standard printer test page and a few sizes of "millimeter" scale type of images would suit the need. They wouldn't have to even be scaled properly, I expect, as long as the grid/scale markings were consistent, so distortion would leap out.
Any ideas or existing templates out there?

See post #10 in this recent thread:

There was no evident interest, so I didn’t bother trying to produce anything better

Too many 'projects'

I would bring along anything you're very familiar with, some newsprint if nothing else. Perhaps have some change in your pocket to help ensure the alignment is good; pick a mag, place a coin that's a little smaller than the field of view and see that it's properly centered and aligned in both eyepieces.
