If this is of any use, PRONI has amongst their collection from the erstwhile UTA, sets of drawings of GNR(I) wagons (reference code UTA/23/AB/1), including a detailed drawing of the GNR(I) weed spraying plant dated 1937. A small image of this drawing was publicised recently in Archives & Records Magazine and it shows the tank wagon with its 6-wheel companion.
