If you go to USFA's webpage and look at the high resolution images, there is an
image of two Henry Nettletons with a box behind them. That box has a label on the bottom that is different than the lid label. Nearly every high resolution image on USFA's webpage with a box in it, the box has that label. There was recently an 5.5" Rinaldo A Carr on Gunbroker, it had the same box with the lower lable, so I know that a gun sold with that box.
The label has "The US Revolver" on it. Below that it has "Forged frame," and "Central fire."
