WTB: Professional Used Matte Box- Arri, Oconnor in Albuquerque, NM

I am looking to buy a professional used matte box from a brand such as Arri or Oconnor. The matte box needs to work on 15mm rods. I am specifically looking for the Oconnor O Box Deluxe but call or text me with what you have and what you are asking. I have cash and lots of equipment to trade also. Thanks!
