Yep I believe so, he must have had the one with the Orange tolex, and one with the black. I don't know if it's true, but I read that the one with the Orange tolex sold for $30,000....
just found some pictures of him with 2! not sure if it's the black one AND the orange one though..
he's been using some Orange's again in recent photo's... can't quite make out what they are though. There's a standby switch and the power switch/ pilot light is on the left side, it threw me off.
