I just came across some potentially useful information on the Photographic Historical Society of Canada's website. http://www.phsc.ca/
For restoring leather coverings and bellows, and to remove mould from an old camera, TALAS Leather Dressing is recommended. Dead Link Removed "This inexpensive mixture of lanolin and Neats Foot Oil is used by libraries as a leather dressing for book covers (any necessary applications of dye or glue should be done before applying the dressing)."
"Potassium lactate (also listed on the Talas web-site under chemicals & deacidification) is used as a leather protection and means to neutralize mould and mildew. Using potassium lactate on bellows may dissolve leather glues. The British Library prefers potassium citrate instead (British Museum leather dressing formula)"
