Paper

Just remembered dad telling me one day that he was sure babaji's electric shop was in hoshiarpur not jalandhar, because when there shortage of paper to practice his maths or notebooks were too expensive(during world war time I guess( he was given those empty bill books to practice his maths on. which also proves the fact that his business wrapped up because the bill books were empty. (may be not enough households in hoshiarpur with electricity in those days)
