...so these are all his Maiden touring/recording kits as far as I know. Unfortunately there is little to no documentation of which kits he used to record the Blaze albums, or which kit was used to record Brave New World- so I’m avoiding speculation there altogether.
He has, on occasion, used smaller kits for TV appearances or brief festival spots, and has probably more than a few additional kits in his traditional "Maiden" configuration that have never seen use on stage with the band.
