Entire Letter from SIR JAMES COLQUHOUN at EDINBURGH but has only an unevenly inked DUMBARTON postmark and no charge marks although not drawn up as a Free Frank - not an easy hand to read - probably carried privately from EDINBURGH and put into the post at DUMBARTON?   DUNBARTONSHIRE, INSTRUCTIONAL.   HAVE A LOOK AT OUR OTHER EBAY AUCTION AND BUY IT NOW ITEMS - MORE ADDED REGULARLY - PLEASE LEAVE FEEDBACK.
