The stuff over the control panel is a vinyl sheet, but not like favlon (or whatever its called) more like the trade stuff that you can get signs made out of, or large decals for cars.
Thats the closest I've found to it! A professional sign maker would have the equipment to make you a piece in whatever pattern or size you wanted!
BTW, the stuff on the MVS cabs seems to become very brittle as it gets old <IMG SRC="smilies/wink.gif" border="0">
