6.5x14 16 lug, triple flange rims. 1950's 3-ply Ludwig shell with clear mahogany interior and solid maple reinforcement rings. The original wrap was removed and replaced with a ply of flame maple and a walnut inlay. All original hardware removed and holes filled. Premier lug casings and a modern strainer and butt end were installed. I asked the guy I purchased this drum Why? He said with apologies that several years ago he was experimenting with this sort of thing. Oh well, he did a real nice job though and it sounds great. Warm, full bodied and resonant, a great players drum!
