Cal-Star Bongs Ad
It is known that Rumph had a relationship with Sarah's Family Bongs. Cal-Star would appear to be a division of Sarah's Family. What is called the "Joystick Bong" here is known as the "Pipe with no known name" on TheRumph.com. The Cal-Star "Wizard" is known as " Wizard Bust Bong" on TheRumph.com.

I suspect most, if not all of these, are Rumph. However I have no evidence of that, as with the exception of one photo of the "Baby Buddha Bong", I have been able to track down little info on the rest.
