What a slice of our industrial/mechanical history. The contents would make a small museum by themselves. In the 1950s a family friend was the local watch and clock repairer with a shop in the town. Looking at the photo here of the four-jar electric parts cleaner reminded me of the one he had. The watch or clock parts were put into cleaning fluid (probably carbon tetrachloride) in a glass jar which sat on a vibrating base. As with the one here, it was mains powered, and just a few minutes were needed to separate any dirt clinging to the brass and steel gears wheels, etc. I'm not sure what "Domestic with a daft code name but a bit of a difference this one" means. Does it refer to the term "horologist" (a watch or clock maker) or the "Camp" coffee name? In the days before coffee powder (now coffee granules), Camp coffee (a liquid mixture of coffee and chicory created by CAMbell Paterson - CAMP? - of R. Paterson & Son in Glasgow.) was just about the only instant coffee available. It was sold in strong bottles, was concentrated, saved space, needed just a few drops per cup or mug - and was used when camping. It did what it said on the bottle. As a Boy Scout, I used it. When on picnics, my family used it. Both the Camp coffee box and the house's contents happily took me back in time.
