I have just aquired a Slingerland snare with the slap-shot strainer. It's a 14X8, wood shell, White Gloss Pearl wrap. The snare wires are tuned indivisually, and are in great shape. the badge # is 480689. Would this put it around 1980-83? Also, would the shell be maple/poplar/maple? It's an awsome sounding snare! Thanks for any help you could give about this drum.
