Celestion G12H30 1971 Greenback T1534

Highly sought after G12H30 55 hz bass resonnance (though the label indicates it's 75 hz, usual mistake from celestion at this time).
Often called the Hendrix speaker, T1534 model (celestion ref of this model, while Marshall's was T1281).
The speaker code indicate it was made 28th august 1971 and it has its original pulsonic cone. Speaker is in great condition with no voice coil rub, rust, unglued spider or any unwanted noise. 

Only thing I would point out though, is a tiny aera of the voice coil's edge that feels kinda soft, like if it had some shock against something in the past. It isnt a crack or tear or anything trough the paper. I've had this speaker for two years of intense playing with high volume range and it never showed any kind of deficiency. It certainly isnt an issue but I tried to take a photo of it.
