I have a 1958 Slingerland Gold Sparkle Drum Set with a 14x20 bass, 9x13 tom, 16x16 tom and 5.5x14 Radio King snare. I'm looking for original coated (except the snare resonant which is clear) Slingerland branded heads both batter and resonant sides from the mid 50's to the mid 60's. The resonant for the bass drum should say Slingerland across the top, preferably the small letter style and my preference for the other heads are the one's that came with the Slingerland stamp that's about midway between the hoop and middle. Must be in at least above average condition and although calfskin is preferred, I'd take plastic also. Condition is a priority. Thanks for looking.
