Just scored this old stone which appears to be a finisher--just not sure if it's a Thuri? There is a small piece of what appears to be an original label on top of the wooden box in one of the seller's photos.

Took a shot in the dark with this one. What say you, honemeisters and aficionados, did I do ok?
