Hello Shirley,
I can supply you a Brenner V4 Contra Drive.

There are a few options with the drive like: anodised spinners, Pyro 600 (recommended) motor or Pyro 650 motor. Let me know if you want an anodised spinner and the colour plus what motor you're after and I'll put together an offer for you.
Also, where are you located?
Another option is the Ralph Schweizer CRS.
