Do you know this razor? (presumably gillette?)

[zatoichi]

Dear safety-razor-users,

I have been shaving with a safety razor for four months, since I discovered the Wilkinson classic in a drugstore. Well, things came as they usually come: I bougth the Merkur HD, then a vintage Gillette Tech, then a 1940`s superspeed, a 1950`s superspeed (just to see if there is a difference...), a Gillette aristocrat and now I am considering to buy a Gillette superspeed red tip because I like heavy razors.
Well, once I discovered my interest in the art of using a safety razor, I asked my grandmother wether she still has some razors from my grandfather. She gave me two razors, one is the razor below.
What is it? I cannot claim that I know much about gillette razors, but I have not seen such a razor since I am browsing e-bay. (I am from Germany, so I use E-bay Germany). You cannot see it so well, but it is a three piece razor. It seems to have the rhombic Gillette logo on it, but it is not clearly recognizable as the metal is quite weathered. There is no date-code, but "Made in USA" is written in the lower right corner of the head, like the other Gillette-razors have it. So what do you think? Some kind of Tech-Model? But with an open comb?
I would be really grateful if one of you could give me some clues.

Never seen one exactly like that before...may be a mismatch (i.e. Gillette head & aftermarket handle).

....could be a Goodwill.

I don't know what it is, but it's not a goodwill.

Welcome Zatoichi,
A fan of the blind swordsman I assume!

I have no Idea what your razor is, as suggested it may be a Murker or M+P handle on a Gillette head -the treads are compatible.

Thank you very much for your suggestions and your warm welcome.
It is quite a good idea that it might be an aftermarket handle. Or it could be possible that my grandfather just put the good parts of two damaged razors together. If this is a gillette head, and I am quite sure that it is, what typ of razor do you think it did belong to once?
What`s a Murker? Do you mean Merkur or is there another brand with this name?
@goosemeplease: yes, I quite like the original Blind-Swordsman films. It`s quite cool . And besides, having a name beginning with "Z" is so practical. I can always find the name quickly in a list.

Well, I think that the photos are not so good, so here are two more:
