That faux grain on the RCA looks sort of like they were trying to mimic an olive burl, though a walnut burl would probably look close. Other then on the curved portions you could probably use the real thing on part of it since most of it is flat. I think you could probably bend burl veneer but sharp radius bends would be tricky since the grain is going everywhere, on this it looks like there is a dividing line right below the dial.
