What has become of this 690 Dumptruk? And what do the initials SLPH stand for? The photo was taken on July 28th 2002 at the Science Museum Wroughton where the 6th Matador Militant Gathering was held. Scottish Land (Development Ltd) was the sole distributor of AEC dump trucks, but despite the prominent Blue Triangle badge as fitted to AEC 10 18 cu yd dump trucks, I suspect this example was actually a later LD55.
