I have to ask, now that you do have a picture why you can 't take the dimensions from the launcher itself. I mean if your a machinist using your calipers shouldn't be to hard, and coming up with your own drawing should be pretty easy as well. As a machinist that what i would do.

I have tried, but the angles and curves along the spine and face of the piece aren't clear - which is why I am asking for a picture of it from the top down.
I have the width being 3/16 inches wide, I'll be checking the pin hole diameter with a gauge pin today at work, but other than that, the low res picture with hazy definition (at least when blown up to measurable size in photoshop) is slowing the process.
I dont have free reign on the machines at work, so I am looking for the best info I can get to get the part done right the first time.
The only dimesnion the launcher has is witdh of the slot where the part goes in, otherwise it's all a blind measure.

I'm not a novice to taking measurements off of pictures, I made a replica of a Renzetti Master series fly tying vise from 2 dimensions on the base, but I had a positive side profile to measure from. That's all I am asking for help with now.
