1993 bigfoot made the smokestone
1994 muddyfox say no no no big foot name theres they then change to ozone which they kept till the end in 1995 but just after the name change mr g foot moved from ozone to softail innovations where he took his design and made the frames just called smokestone (mine) they also stopped in 1995.
