Being a newbie, I just didn't know if this was an easy to fake item, or not.
I thank you and everyone else for their information and patience with my newbie questions.

If this is demonstrated, you know you have a achromatic meniscus that fits your shutter.
How many achromatic meniscus non Kodak portrait cells from other lenses will just happen to fit your shutter ( diameter, thread pitch, male/female)?
You are right however, you will never know whether someone has switched this Kodak portrait lens into this shutter from another, otherwise identical, lens.
