Wanted to buy: Rear Blackwell 100 or Blackwell Disc

I’m looking for a rear Blackwell 100 or a Blackwell disc. If you have one you want to get rid of, please let me know.
Thanks!

I have a disc that is probably 3 or 4 years old. Only ridden in races with less than 600 miles on it. It has a Durace 11-23 cassette and a Conti Sprinter tubular that is not glued. I’ve made the decision to switch my tri bike to Campy to match my road gruppo.

I do have someone else looking at it but will let you know if they pass.
