Identify gear sets - 996tt?

[Quinlan]

Hello all
I formerly owned a 996 turbo which developed 2nd gear pop-out issues. I panicked at the time and looked for repair parts, and ended up buying a stash of parts that the vendor said were for a 996 turbo manual transmission.
Just after the parts arrived I found out that my aftermarket warranty company would not only pay to fix the transmission, but in fact would pay to completely replace it!

So, the parts I purchased went on the shelf.

Now that I have sold the car I am going to put the parts up for sale, but there does not appear to be any logical part numbers on any of the gears.

I have 2 main shafts - one new and one used but in great condition, and I can visually identify these as 996 turbo parts. But the gears are another issue.

I have attached some pics and I wonder if someone could help me identify whether these are in fact for a 996 turbo?

Thanks

By the way, that is dust on the parts, not rust!
