are there any markings or codes on "mesa boogie spec'd" vintage 30's?

[JimAnsell]

I keep reading that the vintage 30's that mesa boogie uses are voiced slightly different, and that they're "Better" sounding or whatever. there is someone local selling one that he claims was pulled from a mesa boogie cabinet. is there any way to tell beyond just taking someones word for it that it is a mesa version?

The Mesa models are T4335 & T4416 from memory - don't recall which is 8 and which is 16Ω sorry. Stamp or sticker.
