They were first released at the Spring 2007 Knob Creek show, and on the corresponding BladeForums Knoboganzaaaa in Desert Olive and Tan Canvas Micarta. I recall seeing them in a couple additional colors later. I passed up on the Knoboganzaaaa offering, but had buyer's regret, so when I went to the next Indy1500 show and they had one of the EH3 Mini Mojos and one EH3 Mini Uncle Mojo, I snagged them both -- I've never been able to find any information about what unit they were made for though.
