These are generic scales found on many vintage french blades. I don't know if TI used them in the past, but it's possible. The pins look a bit mismatched though, so may be they're a replacement.
I don't think it matters too much, though, they are scales that serve the purpose and if anything are period correct. If you want more certainty about the original condition of a razor I think you ought to be looking at nicer stuff.
