This is not an easy item to come by. As illustrated above, the company was incorporated by Royal Charter on 1 November 1881. This share certificate was issued in 1916 and I wonder whether the format was same as the very first certificates issued in 1881. It is rather interesting to see at the very top that liquidation of the company was not completed by May 1951. After the devastation from Japanese Occupation, the company was not financially unable to rebuild the country. They gave up the charter and the company was officially dissolved in June 1946 on North Borneo becoming a crown colony.
The signatories of the directors on this certificate were Vice Admiral Sir Bouverie Clark, KCB and the Hon. Mountstuart Elphinstone. The secretary was Harington G Forbes. In case you wonder how I manage to discipher the signatures, I do have a copy of the North Borneo Handbook issued in 1921 with these details.
