Was watching this video of Bonham and something caught my eye. It looks as though his 14" was retro-fitted with a Rogers swivomatic arm, and is also on a snare stand? I've seen him use the snare stand for his Visatlites, and a rail consolate on his Green Sparkle kit. I never noticed this before though.

Found a couple still shots that show both.
