Jim although I sold my Vigilants, bins, tripod, controllers etc some years ago I still have a few curiosities that I have hung onto. Two silver-plated Vigilants 3" long that were mounted on ashtrays to give to defence ministers at arms fairs, an instructors book (civilian one predating any MOD publications), the illustrated design publication before it was named Vigilant & I think I have one sighting monocular.
If you are googling also look for "Vigilante" this is the wrong name but often gets misnamed as that. Just as my Shorland gets wrongly called a Shortland or a Shoreland, ggrrrr
