My memory fails me, just thought a review of old parts suppliers and what happened to them would be interesting.
The ones I can recall include Filtron, Torque
Engineering, Circle Industries, Van Tech, Curnutt, Betor, Ceriani,Bassani, and many more I cannot recall.
The only rumor I can recall is that UniFilter, then an upstart, bought the Fitron name, anyone know if this is true plus any other stories of interest about the now defunct brands.
