It's French (very tiny chance it's Swiss) because of the info stamped on that fixed cup: 35 x P1 means FR threading, and I'm pretty sure that Sugino would add an "S" to that if it is Swiss (and has LH threading). And the width is 68mm. You'll know for sure when you try to unscrew it: if it's conventional RH threading or LH, you'll find out the only way.

I did a quick visual search of BB shells and haven't found anything exactly like that one, but seen a couple that are sort of similar, and so I'm going to present another idea: it might be German. Don't know enough about German brands (not many around, especially in the US) to know if they would use FR threading in a BB, but perhaps somebody here knows.
Is the headset a standard threading (British/Italian/ISO) and the stem quill a 22.2mm, or is the stem quill 22.0mm?

BTW: there was a thread earlier this year for a Takhion time trial bike for sale, I think I might have "outed" that one. Very interesting bikes and history!
