On this list of film holder specifications I found one film holder that had a major deviation in one dimension from all the others and it makes the design completely different. I would have considered it a mistake but I happen to have a film holder in that size and the dimensions fit the chart even though I know for a fact that the other film holders I've seen in that size aren't like the design on the chart and my film holder. Can you find the that one size and the dimension that would make it unlike the others?
