Greetings, War promotes safety devices, a shovel over the head makes wonderful sense to me, everything fired into the sky or the fall-out from explosions has to come down. I understand that WW 11 pilots used a seat plate and often a back plate before they were part of the equipment, certainly bomb aimers lying flat, used a steel plate to cover the 'essential bits'. Gun shields on ships was a thin plate but the illusion of protection was there. Up to date, workers on building sites in England would not be seen dead in safety helmets until they became law. Having done so, many a head has been protected from 'knocks and bangs'. Peter Peter Gower wrote: > But remember Canadian Sam Hughes experiment with the McAdam shovel.
