I have one I struggle with. It is a 38/44 HD from 1936 that went to the Amsterdam, NY police department (from a Jinks letter).
Some previous owner thought it would look better if they stripped the blue off. They must have taken naval jelly or something and they stripped every bit of blue off of it. No marks or scratches - never been buffed. Really beautiful condition. But zero finish.
It's no longer original...and I am really tempted to have it reblued. It looks almost like it could be degreased and dropped in the tank.
