I can't seem to find any info on these, buy they sound intriguing to say the least. Please share a pic if you have one! I've played a Meazzi Hollywood President kit with a tympani mechanism in the floor tom though.

I've never seen one in person. But it seems that when the Roto Toms first came out they had numerous options. Different stands, half and whole shells you could add, rapid tuning pitch pedal. Unfortunately seems that the 6",8",10",12" were the most popular and everything else was quickly done in. I know until somewhat recently you could still get up to the 16" size, but I don't think those are made anymore either. Found a catalog with all the bells and whistles. But man those Timpanello's look rad.

Not sure if it took, as I forgot to attach what I had for catalog details ....
