Mr Ocheltree was NOT around for any of Zeps recordings Bonham mainly tuned his own kits, Jimmy Page has stated this on many occasions during interviews. If anyone knows it would be Mick Hinton, now sadly passed.
I heard he used shredded news paper in his bass drum for studio recordings if that helps, also heard he lined the bass drum with silver foil on his early kit (pre Thermogloss) Green sparkle in 22 13 16 in an attempt to make it louder (as if he needed to be louder). Never saw one of his kits with a felt strip on the front! ever.
The video above is helpful for sure but not accurate it is only Ocheltree's take on what he thought Bonham might have done but hey he sold a few DVD's of the back of his very minor Zeppelin experience.
The snare used was rumoured to be a 1920's brass tube lug Ludwig snare 6.5 x 14, but again this is subject to opinion.
He also used LM 400 snares there are early pictures where you can see one sitting on the floor next to his kit probably as a backup in case of head breakage.
