The TracII are the best of the cartridge type blades, many still use those. Clean it up and it will probably work and look real nice!

I've seen a LOT of razors but I've never seen this one. It's very interesting, hopefully someone here will have a solid answer for you

Does anything move where the blade goes such doors or pivots...

Looks like it might be an Injector possibly. Could you post closer pics of where the blade goes in?
