This Leedy double bass drum internal dampener is believed to have been purchased from Johnny Frost's Drum Shop in Soho, London in 1938.
The double bass drum dampener is a thing of beauty, either fitting through a drilled hole, or through the air vent of the bass drum, the dampener allows both heads to be dampened at the same time.
I have been able to find no other examples of this dampener, so if you do have any details please do share them with us (everyday is a school day!)
It is in superb condition, working as it should, with the original felts still in great condition.
