Correct it is a red dellortto, but not the standard type. Its actually a dellortto flat slide carb, so still has all the same benefits\ characteristics or a keihn. When they have been used before they have been very tempermental (even more so then the keihn) but aparently paxau has done some work on them to improve things. I no that chris pearson of splatshop.com is testing one so could shortly be the man to contact if you wanted the same carb as the top boys.
