Andy, Although issued as part of the C.E.S with Vehicle Etc. It was Rarely If at all worn on a belt kit in the field on Exercise. It was too cumbersome & was kept stowed anywhere you could in the vehicle concerned. They were originaly designed to go on the 1944 patt Webbing where the Bottom of the waistbelt had eyelets for that purpose. (& other Kit) In practice, IF, carried. It was generally strapped crosswise on the outside of the Bumroll (Poncho Carrier) of the 58 web set. The scabbard as you know, has a web beltloop on the rear, & this was really the only way you COULD carry one on a 58 Patt belt if you actually wanted to. In Reality, you had so much junk to lug around. ANYTHING you didnt want to carry, you didnt, IF you could get by without it! Try getting in & out a Ferret with even JUST a set of 58 webbing on, & you WILL see why it was not worn on web sets by vehicle crews! :-D
