Lifter button finish.
 

I know that later lifters with the 1pc buttons are blued. But early guns with 2pc buttons, what are they? Anyone have any high condition examples that can lend some info. I know the bar is colored, but what about the button and screw?
All my books are currently packed away.

Your books won't help. We need high condition guns to examine.

I know where one is that i ised to own and i am inquiring with the current owner on it.

Contact with him suggests colored for both parts of the button.
