Hi, I recently acquired a Ludwig mahogany 8 X 12 green sparkle shell that is faded to a wierd shade of yellow. There is no stamp on the inside, but it definitely had a keystone badge and large Ludwig classic lugs on it for a long time. My question is, did Ludwig use the larger classic lugs on any of their 12 inch 3 ply mahogany toms? Is this really a Ludwig green sparkle 60's tom? The shell itself is really is in really great shape. Any help would be great. Thanks.
