Datasheet for AC128/ Germanium Transistors in Fuzz Face

[amallon]

Hi there, this is my first post so apologies if its not in the correct place!

I'm a final year undergrad student studying Electronics with Music and need to locate a datasheet of an AC128 Transistor or similar germanium transistors used in a Fuzz Face distortion pedal. I see that some people have posted spice models for this, however it would be great if there were some characteristic graphs that I could compare this to.

I'm quite new to all of this, so any tips would be greatly appreciated.

Cheers.

The graph is on you, I guess.
All that I could find is the parameters.
