I have for sale or trade a Zeiss conquest V4 6-24x50. This has a 30mm tube, the ZBR-1 non illuminated reticle, side parallax adjustment and external elevation turret. It is I excellent condition. No ring marks. Asking $900 or trade for a different Zeiss or Swarovski scope of similar power of equal value and a standard duplex reticle. Can add cash if needed.
