SBT03 A vintage and very rare 1974 Oman first day military cover of the Britten Norman Defender Delivery Flight from the Sultan Of Oman's Air Force which was specially carried onto the Defender plane and details on the front of the card the officers which personally carried the FDC for its authenticity - truly outstanding condition too (both sides scanned and merged into one image). I have searched the web and this seems extremely scarce.
