I do find it interesting, the latest find would only have "J. Plant" as a signature. For the time being, I am going to work under the assumption that it was early in on the Plant corkscrew dynasty. Hopefully some answers will be discovered soon, as I have started researching the Wolverhampton Plant’s history… (Boy, do I really need the semester to start).
The syroco monk lux clock arrived today, as did the pair of Yankee # 1 bar screws… I am still waiting on a stylized cat Bosse corkscrew, but given it is making its trek from Austria, it could take a little while longer.
