One of my 1901s has an unbelievable brass "substitute" for the ejector knob. I've checked several threads and I want to confirm that the knob's threads are right-hand before I make a mistake.
I am relatively sure that the threads are right hand 6-36, the same as the Army Special and Official Police that came later. If it doesn't come loose with a relatively small amount of force, soak it in Kroil or CorrosionX overnight.
