You might want to pick up a copy of ANSI Standard PH3.108-1988 for 11x14 double cut film holder specifications. The standard lists all current dimensions for film holders (ranging in size from 2 1/4x3 1/4 up through 16x20, I think...I don't have a copy of it in front of me at the moment but I'll try to dig it out and email the 11x14 specs to you if you want...I also saw them posted on the internet recently but didn't bookmark the URL...Googling should find it).
Unless you are trying to design around new Fidelity holder dimensions, I think you will run into problems by just borrowing any old holder for comparison. Many of the old holders/cameras were not of a standard size. There are Korona, Sterling, Fidelity, Hoffman, Graphic, Kodak, Burke & James, etc., holders and each may have different dimensions, not only outside but inside (t-distance, etc.) as well.
