Prams. Trevor Chaplin decided, were not what they used to be. When he was a lad in the North-East, prams were vehicles of substance, designed by the spiritual descendants of Brunel and Stephenson, and built by time-served craftsmen, wise old welders, blacksmiths and sheet-metal workers with grey-flecked hair. A pram was high, wide and handsome. It would scrape the paintwork on both sides of the hall simultaneously. On the road it would carry, with ease, the designated baby, plus a week's groceries, a couple of footballs, supplementary kids hitching a lift, fish and chips for the family and still have room left over for a bag of coal.
