I've often wondered why Ludwig didn't make wood shell Super Sensitives in the '60s other than marching snares. Yours sound pretty cool. Thanks for the information.It's a 5x14 ten lug SS. 3 ply maple interior w/ 7xx,xxx keystone badge. Opposite the badge hole there's another grommeted vent hole too. Black diamond wrap. It's a "special order" drum I think?
