Depending on the time frame, Bohnam used a few different snare drums:
Pre Zeppelin (1963-68) era: 5x14" Keystone Badge Ludwig Supra Phonic COB Snare
Early Zeppelin (1968) era: 20's/30's COB Oval Badge Ludwig & Ludwig Tube Lug Snare
Led Zeppelin Tours (1969-80), Studio (1970-79) era: 6.5x14" Olive Badge Chrome Supraphonic Snare Ludalloy 402 series
As
The Ocean was on
Houses Of The Holy, which was released on March 28, 1973, this was recorded in 1972. So based on that he was playing a 6.5x14" Olive Badge Chrome Supraphonic Snare Ludalloy 402 series...
These drums can be found in garage sales across America for 50 bucks and they are utterly common. At your better music stores that sell used gear, these can still be had for 100-150 bucks in varying conditions.
