You can see Ringo using this style of Hi-Hat Tambourine Bar in the Get Back documentary, the Let It Be movie and album photos. You can hear this tambourine on the Beatles' later version of One After 909.
 
This instrument is actually called a Tamba-Ching by La Playa, after years of patiently searching I was lucky to find one and was never able to locate another.  Through reverse engineering, this tambourine bar is manufactured to the original specifications.
 
The main components consist of a lightweight laser-cut aluminum body with a bead blast finish and five sets of steel jangles that create a crispy bright sound.
 
NOTE: I have included one of these hi-hat tambourine bars with Ringo's 1967 Ludwig Hollywood maple drum kit.
