Part of Figure 10 from the 1962 reprint of Joseph Moxon's Mechanick Exercises on the Whole Art of Printing Edited by Herbert Davis and Harry Carter. Page 405. The original caption states: 'Typefounder's moulds probably of the early 19th century, one closed and another open. University Press, Oxford (the metal parts are 2 1/2 in. square).

There is something strange about the wood of this upper part of the mould. It would be difficult to put a matrix into this mould?
