Definitely not the original speaker! It was hanging on by only

Only rated for 60 Watts continuous sine wave:

** That was a great guitar speaker in its day.
Alnico magnet, 2.5 inch VC, 103dB/watt sensitivity and rated for CONTINUOUS sine wave power of 60 watts rms !!
Be rated at 250 watts by most makers today.
Ought to be worth re-coning.
