Technical Banger distributor?

Looking for a new distributor for my Riley 2 port . Banger guys what say you?

 

What are you running now? Hard to tell from the pic

 

Modern? vintage? centrifugal advance? whats on your mind?

 

The one in it is from a Mazda. Stan Vermeal built the engine. Never happy with it.
Just seeing what others are using.

 

F&S distributor is basically a Petronix unit built specifically for Model A's.
