How common are the 18s 21j a6p Bunn Specials? I picked one of for a decent price and wondered just how common they are.

I have a few Illinois but I am far from being anything close to knowing that much about them.

I also wonder what are the styles for the DMK effect available for the 6 positions versions.

Also mine appears to have the correct gothic script dial but there appears to be some styles for the gothic dial what are they?
