I based mine, back in the late 90's, off of #2. Used basically the same one as you listed. I did that one because it was going into a Remington and then later for the '72 Open Top, if I deemed necessary.
Now if it was to be used in or strictly for the Richards then I would go with #3. Really like that label and they kept the same general pattern for the SAA 45 boxes.
But for me, now, I just don't feel the need to do all the work to create #3 even though I have the Richards II in 44Spec and will only shoot 44Colts in it. No-one but me would appreciate or see that work or effort, since I don't shoot competition any longer.
So my vote is #2 since I believe you are putting them in your 'new' '72's.
