I have an eyepiece that is on loan to me from the local astronomy club. It has 1/2" FL on it. there are no other markings on it. It is about an inch tall machined out of a single peice of aluminum, which has been anodized black. I don't have a picture of it ATM but I will attach one later.
I am trying to figure out what this is so that I can calculate the magnification from it.
