Geno,
What do you carry in camp that would need a corkscrew?!?!?!
The center piece came with an unusual carring case, a 10ga empty brass shell, I don't think it was a Parker though.
So a number of these corkscrews have been seen. The first one for me. They must have been somewhat common.
Its interesting that the patent doesn't come up for the Lockyer item.
