Got many of both the ProTank 2 mini and the Davide mini. ProTank 2 mini comes with a gunmetal colored bottom. Scratch off verified. The Davide mini is a shiny silver. Could be later made up-graded mini's came with the silver bottom, but I just use an AFC and rebuild the coils to get me "there".![]()
Yeah - I expect I got them with a couple of ProTanks I got off the classies. I've never owned a Davide, but that doesn't mean much since I've grabbed... "one or two things" that were used previously.

This "research" we did last night, taught me that they were somewhat universal, and I may actually have some need for them (after I run through a few more ceramic coils from another tank/clearo that I could not name right now.
But, ultimately, I learned what they are. And no class I ever took in school was nearly as much fun as this "learning experience" was/is.

I truly do love this place (ECF).
