Inherited Razor. Identification and history help.

[Stig]

This razor belonged to my great grandfather and was recently given to me by my father as I mentioned my interest in beginning to shave with a straight razor. I'm a complete newbie to this style of shaving so any help with the following questions would be greatly appreciated.

I'd just like to know what kind of razor it is, its history, and its potential value if any. I have no interest in selling it, I'm simply curious.

Lastly, would it be possible to make it usable again? And what would be the best way of going about doing that?

Thank you for your help and expertise.
