As their respective names could be found on the business in 1885 and on the manure truck in 1955, it would appear that the Jones family had been in the manure disposal business for a long time (at least a period of 71 years).
Whether they were still doing so or had moved into a different business by 1985 remains unknown.
Behind the scenes
