The stencil wasn't on the inside, I jsut mean when I gopt int inside my house, that back is off ebcause I wanted to check the speakers (once I'd gone 'Cool, Cockney Rebel', that was the main thing I wanted to check). This is the front:
The badge is sideways so when you flip it on its side to stack up off the wheels it looks right. Serial dates it 71/72, but the speakers apparently date it 75, so they might have been replaced after hard touring, or the dudes on the vintage amp forum are wrong (they are currently arguing over how the cab serial numbers work). If anyone can give that chap a shout, that would be cool.
