SAS special Forces Trimble Navigation Unit And Vehicle Mount Very Rare Mil Spec

  

SAS special Forces Trimble Navigation Unit And Vehicle Mount Very Rare Mil Spec. Genuine item I have tested it and scrolled through the options and it appears to work as expected some options can be navigated. I cannot test accurately as I don't have the aerial. It takes a batteries which are not included.

Please see the attached pictures which shows it working. A very rare item to find with original bag which is grubby. May show signs of wear and use age.
