GT have you looked up "valve sludger"? It is the lost piece of the first auger attempt by the Truro Co so named in the Mccully letter I keep referring to.
I had not searched that exact phrase. We can add it to the collection of nomenclature for these augers. "valve sludger" seems to have a fuller body of usage than the other variations, with the AI summary even mentioning the chisel that they talk about swapping in when the point wouldn't do. That "valve" mechanism is crucial for the samples they purportedly brought up.
