Yes thats a re-necked A-50 by the look of the bridge placement! I'd say 40's-50's by the side burst I seen? And I don't think thats the "Clarence-28"...
It happens, seen it too many times! I'm sure the top is dented in a bit also from the bridge feet "Base" I've corrected that by fitting bases to full...
Tony sure could play Clarence Whites old "Bone!" What a guitar man! Tony sure could pull the tone out of that ole Gal! I heard a story from my Uncle...
