Howdy guys, seems much has changed here since I have been away. I found this thingy in a box and can't for the life of me figure it out. I'm sure it will be simple once someone tells me what it did.
It's made of brass, the two halves are held together by the little tits on the locking rings, there is threaded holes in the Halves that I assume would hold a scew to keep it locked in place[screws were missing] and it is bothering me.
Whole thing together.
