I found this on someone’s website the other day. They advertised a folding gutta percha corkscrew. And, while there was no picture, I assumed that what they called gutta percha corkscrew, was actually an 1851 goodyear patent indian rubber roundlet. Well, after several emails of negotiation and pictures, the corkscrew is heading to 16 Kingston! I will look at it closely to see if it is marked…
And, yes… it is the goodyear patent!
