I'd like to mount a Fujinon 90 to a Copal #0 that only has an f stop blank scale. What are some solutions and sources for getting a proper scale or making one with the correct spacing?

I make mine on my computer printer... use the formula to calculate and print on stick-on label paper.

The spacing was determined with 3 complementary methhods:
1) Pictures of the lens with the correct scale were obtained on the internet and alignment of the aperture numbers and the shutter speed numbers was noted.
2) Entrance pupil size of the iris was measured and used to and plotted f-stop numbers along the linear path of the aperture lever
3) Horseman film-plane exposure meter was used to double check the scale.
4) Trial and error was used to print out the appropriate scale by altering text size, font, and spacing on the label machine.
