Master Cylinder

[Challenger in NC]

I believe this is a very common manual brake unit that probably has little worth. I've had it sitting around for years and am looking to get rid of some garage clutter. Is this worth trying to sell or should I just scrap it? I'd give it away but probably not worth shipping.

I can't make out the whole casting number but it doesn't look like an OEM Bendix part.  The lid certainly isn't.  Unless it's an original Bendix core it has no value except as maybe a doorstop or shop ash tray or something.
