Sunday i ve bought ( for E 5 .00 that be about us 6.00) a verry strange old bongo on a flee market . 
The skin is attached bij a hoop arround the rim and looks like the thing  with wich you screw  the nozzle on the end of your garden hose .
On the insides are 2 bars with a spindle through them  witch ends in a ring. 
You tune the bongo bij turning the spindle that pushes the rim outwards wich in turn tightens the skin . 
 
 The kettels are made of light and dark collored staves .
Is there anybody who knows anything about this bongo ?
Leedy 2 maybe ?
thanx in advace
