Federer uses a frame which is made in the K6.1 Tour mould. Whether it's different on the inside or not is not known. But the dimensions, weight, balance, swing-weight, grip shape and size are all known.

I can see that they probably use the same mold, but that isn't something that the manufacturer has ever disputed (from what I can tell). It's the composition and the people posting that they "know" it is this racket or that. That's all I'm saying. 95% of the information in this section is purely speculation.
That being said, there are a few respected members here who currently either work in the industry, string on/or for the tour or have connections in the industry. But there is far more misinformation being posted as factual.
