Hi gunnellett!I have 5 Slingerland Deluxe Student snare drums in my collection, 2 of which are all original. Those 2 drums use the thicker snare string like your drum. So, yes, it was what Slingerland was using at the time. Oh, and one of those drums is also Sparkling Gold Pearl like yours, but somewhat faded. Finding one as nice as yours means it was most likely in the case for decades and not exposed to UV sunlight. Congrats on a great looking snare drum!Forgot to mention about the snare beds. They were on the deep side...and many are not properly centered! -Mark
5 Deluxe Student snares..... lucky man!
