I don't consider this a vintage kit so I posted here. My buddy has a 12/13/16/22 kit in faded white wrap. The inside is black as are the rounded bearing edges. Frankly, it looks like someone took matte black spray paint to it, but they are factory. The inside looks like luan (large vertical grains/lines) and I am sure it's not maple. My research indicates the kit is birch/poplar. Does anyone know the shell makeup & # of plies? These are the ones with separate lugs up and down (not connected) that sort of look like Ludwig classic lugs but more boxy and a little bigger. They are made in Taiwan....I don't have pics, sorry......thank you!
