I've got a chance to pick up a '79 2204. It has no mods, and looks to be all original. Is $1400 a fair price? Here are a few pics. Circuit board looks all original to me, I think... Is the rusted handle a big deal? I doubt it. Feel free to give me your insights if need be. Any help is greatly appreciated, as this will be my first Marshall. I've been a vintage Fender guy forever.
