I don't know the origin of this piece but it looks to be of the period (the two calendar inserts you see above are for August and September 1914). The round hole between them would have housed a clock, there are letter scales, drawers and compartments for stamps, ink, rubber bands, cheque book, 'letters answered' and 'letters unanswered', pens, fasteners, wax and luggage labels,
and the blotter incorporates what looks to be a ceramic 'slate' (anyone know the correct term?) for memoranda and one for engagements.
And when you've finished your correspondence for the day, you post it in the box in the hall!
*The 'z' is silent, and the name is Gaelic for 'field of corn', I understand.
