When my father transfered from the Army desert salvage, to the RAF air sea rescue. They did not have many spares, he knew where some Napier Lion engines were buried in the desert and they went and dug them up.Using them in the boats. It could have been an area used and vacated by 40 ASP. I also remember him saying he had watched an amunition dump being blown up to deny the stocks to the enemy, He watched the shock wave travel accross the desert floor. I have got singed eybrows just watching the video about Hot Forging, working in those conditiond day after day.
