Lets not forget chaldrons if we are talking about coal
Willian in Coasting trade rightly castigated Nef and Hoskins for confusing
the different actual weights of local measures.
A London chaldron was 26 cwt
Newcastle 53 1/2 cwt
Milford Haven chaldron 2 tons
However the Newcastle units varied over time; see `A Glossary of Terms used in
the Coal Trade of Norhtumberland & Durham' by G C Greenwell.

Museum), 1987.
