We thank John Hillier for providing both his stellar atmosphere code and useful IR photometry. We are grateful to Allan Willis and Lindsey Smith for their contributions to successful telescope applications, and to Ian Howarth and Angela Cotera who kindly let us take a peek at their IR spectra of Brey 89. PAC and LJS acknowledge financial support from PPARC. Calculations have been performed at the CRAY Y-MP8/128 of the RAL Atlas centre and at the UCL node of the U.K. STARLINK facility. We appreciate the support of the staff of the Mount Stromlo and Anglo-Australian Observatories, particularly over two Christmas periods for the latter. We have used observations made with the NASA/ESA Hubble Space Telescope, obtained from the data archive at the Space Telescope Science Institute. STScI is operated by the Association of Universities for Research in Astronomy, Inc. under the NASA contract NAS 5-26555. This work has also made use of the SIMBAD database, operated at the CDS, Strasbourg, France.
