Old school looks all in the finish Jimmy. There got to be a source for the blue checkered vinyl looking stuff and proper grillcloth. May want to add a strip of 1/4" around the face of the cab so it looks like it's made of 3/4" material and the old style corner hardware will fit properly. There's pics either on TB or BillF's site of a guy who finished an O15 to look like a mid-70's or newer ampeg cab complete with the white piping.
