I too have pondered over this, and other similar trailer loads, seen on D Day photos.
Les: hadn't thought of baloon cylenders before but I thought that the initial baloons were the smaller ones taken (ready inflated) from the landing craft which flew them on passage. have not seen any referance to vehicles/trailers associated with the initial BB units
Sapper: how about rolls of PBS as mentioned recently in relation to the possible Tar Boiler.
At this site
http://www.6juin1944.com/assaut/gold...page=69landing there are some fairly good landing tables for Gold Beach - these include 6 "Freuhauf" trailers landed for 235 Fld Pk Co and 3 of same plus 2 "20 Ton low loading Trlr" for 51 Mech Equip Sect but no mention of what any carried
