Re:

Good point , my Gran Sport and indeed all Gran Sport axles are black oxide type finish, so yours can't be from that range

I am a lucky man, I bought the 115,5 mm axle from my friend, when checking everything over the old axle that came out of my bike is also 115,5 mm silver in color and marked 70SS, my crank is the newer type With a 8 in diamond date mark making it a 78. The bike came to me With Stronglight cranks, and I bought the crank with no idea that there is different types out there.

Everything fits nicely together and the chain line is perfect.

Now I need to build some wheels.
