Pearl P202TW

In the photo, this is the Pearl model P202TW. A great double-pedal!
Its specifications:
<ul> double-chain </ul>
<ul> advance of the adjustable heel </ul>
<ul> beat 4-head (felt flat, domed felt, plastic dish, plastic domed </ul>
<ul> clamping jaw against the bass drum is adjacent to the pedal and not underneath, which is convenient </ul>

One of the best models all brands, even today (I played on this model already in 1997).

You just know she does not age well:
Oxidation of the joints at the transmission bar
Bats felt, it disintegrates, but there is plastic bats
