Hi and welcome to Priory Antiques, we have here a super quality. Item that if we are honest we know nothing about. This has come in with a selection of amazing items and this one is a Flicker Photometer. It has a thread on the base for mounting and I have added a video to show that it spins freely but that's really as much as we know about one of these.
I hope from the pictures you can see the quality and that someone can give this a new home.
