Hi Tyneside ,Take note of the way those 10 stone bags of flour are loaded on Ranks 8 wheelers each two upright bags barrowed onto the platform and set up against the first three rows cross butteressed. Next sheet the load and tie about 4 cross ropes over the sheet at equal points along the platform length and across the back rows and away you go. This was the regular way most flour millers dispatched their products back in the 1960s I have hauled numerous loads of flour this way, some out of Ranks without any mishap.
Cheers, Leyland 600.
