If your camera has a red window, you can use that to determine where on the paper the numbers need to be with respect to the edges of the paper.
And if you measure the film gate, you will most likely find that it is essentially twice the size (4.5" lengthwise) as in a 6x6 camera. So you can use the spacing on a 120 roll as a guide.
Depending on where the window is on your 116 camera, you may find that the spacing for frame numbers 2, 4, 6, 8 and 10 in the 6x6 set of numbers on the 120 backing paper will work, although not with optimum efficiency. The most efficient use would most likely be had from markings half-way between the following existing markings: 1 and 2, 3 and 4, 5 and 6, 7 and 8, 9 and 10 and 11 and 12 (all of course in the 2 1/4 x 2 1/4 row of numbers).
Hope this helps.
By the way, 616 film should have similar numbers, so if you find any of those they should work as a template.
