i have one apiece. in usa, darts came red. mini's came red/orange. a definite color difference......my understanding, mini's were targeted euro market. darts usa market....mini's still managed to find their way here. mini's also came in a variety of color. darts red only.....i would think, if you saw anything other than red/orange mini here, it would be super rare.
reverse cut gears, 3 shoe clutch are a few diffs....rings are easy to come by. treats, 2fast, dos cycles, denny's, myron's, i use them all for aftermarket, nos parts.....
