In WW2 when posted to a new Unit in my Regiment (Royal Electrical and Mechanical Engineers (REME)), we were not allowed out of camp for two weeks; my first posting was to 25 Command Workshops, Grantown-on-Spey.
The fortnight elapsed and I applied for a 48-hour pass. When the 'bosses' realised that I was in 'home' country, another rule kicked in, and I was posted, within days, to 20 Coastal Defence Maintenance Unit (20 CDMU), Leith. My job there was to look after the diesel-generators (Lister 22Kw and Ruston 50Kw) on the islands in the Firth of Forth and elsewhere. I would go down to Leith Docks, with my tool box and injectors, and ask to be taken anywhere between Montrose and the English Border, by RASC Launch.
There were about a dozen of us and our workshop had been a small garage in a quiet lane in Leith, opposite the back door of a bakery. I had an 6X6ft garden shed within the workshop where I operated on diesel injectors and pumps. I even had a certificate which allowed me to take the cover off a CAV pump! We did not have a barracks, did our own catering, and slept in Leith Fort, on straw palliases on the stone floor of a rather large room. We were not alone as various other Units slept there too.
