The correspondence is 4 letters, one written May 27 1893, and then June 23, June 24 & June 25 1900. All are on headed Royal Carmarthen Artillery Note paper from Fort Popton, Milford Haven and are accompanied by 2 envelopes addressed to Lady Drummond.
I am happy to show them to you, if you are able to let me have details, I should be able to scan them and send them to you via email or hard copy! I have them as my father used to deal in historical documents etc for a living and following his death have inherited these items.
regards
Simon
