It was just some ideas they were throwing around and never made it. I seen they had a couple different designs when they first came out sombody on here had posted some pics but your gonna have to search.
Been awhile since I've been on here, but is the a new DUO coming out? Love mine like crazy and would like to see one released with the new stamp! Any info is greatly appreciated
It is a prototype that never made it. They have that one with the 454 design-gloss paint and another one with the same scheme but with flat non-gloss paint job.
