Terry's is 90's - I used the women's saddles with the big hole in the middle. Liberator. Had one on an Amp B2 and a C16R.Wtb SST in it's many variations. My tookas likes the super early version that is pretty much flat with the rails tucked up and with no up curve in the back and no down sloped nose. Unfortunately that version is really hard to find.
Or I like the Terry Fly or Butterfly. They might not be vintage mtn per sey, they look pretty good on a 90's mtn bike. And they come in fancy titanium flavors too.
