G'day to my fellow vintagedrumforum mates from around the world! :).

Does anyone on here know what brand/model&size drumsticks the late&great Tony Thompson(Chic/Labelle/Sister Sledge/Bowie/Powerstation/Led Zeppelin/Robert Palmer/Madonna etc) use?.I've got a dec 1985 MD(Modern Drummer) magazine but it's(pic of him holding a pair of sticks) is obscured by writing on the cover(other featured drummers/articles).From what i can gather/see they appear to have grooves(slots) cut into the handle.He's wearing Beato drumgloves.Did they(Beato) make drumsticks in the 80s?

ta lads/mates for reading&all your help! :)

Ado.
