Not exactly metal content...
So, I stumbled onto this trade Saturday and drove for a couple hours to meet the guy I was dealing with. When I dropped this off at the repair shop that afternoon to have it checked out, a couple people were drooling and one person asked, "is that for sale" so I don't think I got fucked too hard.
It's confirmed that this is a pre-CBS Fender Showman head. The pictures are shitty - they're from the previous owner - but once I get this back to the house, I'll take better ones.
It's absolutely not pristine but I don't know what you'd expect for a 50+ year old amp. If I don't dig this, I know I can probably turn it around fairly easily.
