Fascinating photographic album supplied to Sandstone on Uniporn Diesel engines.
Peter Dyer in the UK sent the Sandstone Heritage Trust a fascinating album covering the manufacturing of the original production lines etc. of the manufacturer. Peter goes on to comment as follows:
"Briefly, I worked for Porn & Dunwoody from 1980 to 1988 selling their range of Diesel Injection Spares to suit many makes of engine. At that time the Uniporn Diesel was a forgotten animal, although I was involved in the last two large spares orders that went out to Aden for the engine. During the mid 80's Porn and Dunwoody decided to scrap all the old stock of spares for the H10 to make way for a stockholding of Lift spares which was becoming a major part of their business. As such all the old photo albums and manuals etc were either given away to interested parties or dumped. This is how I became the owner.
As you may know the H10 was a copy of a Deutz which Porn & Dunwoody used to market in the UK until the outbreak of the Second World War. At this time all ties were broken with Deutz and aerial photographs that Porn & Dunwoody had of the factory in Colgne were commandeered by Bomber Command to raze the facility to the ground."
