Three months of his training was on refrigerators with instructor Fred Buddle here he recalls an unexpected trip out to the Knock John Naval Fort in the summer of 1946

"Having repaired the Captain of the Dockyard's fridge in his large Dockyard house which turned into a day long job! We lifted the fridge upside down to allow the gas to flow back to the bottom of the casing, which took about 2 minutes, after which we had several cups of tea and smokes, then took a strolled around the yard arriving back in time to clock off, you can imagine we were tired out!"

"The next day Fred informed me that we were going to a Naval Fort off Herne Bay to repair their rather larger fridge, and said we'd to take sandwiches. The boat would apparently wait until we'd finished and then bring us back home"

"Boarding the Tug we steamed through the Minster & Shoeburyness Boom made of old hulks for defense & shipping control was a strange experience. Arriving at the Fort we were confronted with two massive cylindrical concrete uprights in the water and a huge platform across the top on which were Anti-Aircraft Guns. The Tug crew said they were off to Harwich and had no instructions to wait for us!"

"After climbing up the long slippery ladder we were greeted by half a dozen sailors, one being Sheerness lad Ginger Murdock, his mother had a small ice cream shop opposite the 'Ship on Shore'. He explained the fridge was at the very bottom of one of the large legs and held enough food for the Forts Wartime compliment of 120 men for 6 weeks, but in peacetime the Forts were maintained purely for navigational safety reasons by a caretaker crew of six"

"There were stairs to the bottom but Ginger said we could use the lift. This was a three foot square side less ammunition hoist, as the 'lift' was hurtling down I looked up and saw Ginger with a broom trying to knock the 'off' switch on the opposite side of the lift well, which he managed to do amidst lots of laughter as we stopped a at the bottom with a shudder"

"Fred & I repaired the fridge and then sunned ourselves on top of the platform, suddenly a coastal pleasure boat circled the Fort with the Skipper telling his 20 or so passengers about the Forts. Just for fun we decided to 'man the gun' training it on the vessel much to the consternation its skipper & occupants"

"Around 7 o'clock that evening our adventure came to an end as our Tug returned to collected us, we'd hoped we'd been forgotten. With a nap on the way home we congratulated ourselves on a job well done!"

"As we used to say in the Dockyard - Give us the jobs and we will finish the tools"

"I did pop in to see Ginger Murdock's Mother to pass on his wishes my reward was a rather nice Ice Cream"
