I have a brand new WO 2" diagonal (refractor style) with the 1.25" adaptor. Both use brass compression rings to tighten. I have the original plastic caps but I do not have the original box. I bought this diagonal for a new refractor which still has not arrived. This diagonal has never been used. I am willing to sell for $90 with free shipping in the CONUS. PayPal (No fee) or Postal MO please. I can e-mail a picture if interested.
