Mold on leather

Can anyone recommend some method, procedure, or compound that will
remove mildew from World War II era leather artifacts?

The item in question is an unissued Boyt (a government contractor)
hip holster for the US .45 Automatic pistol. It is dated "42"
(1942). Although unissued, it was stored for years in a dark closet
in a private residence. It has been carefully wiped clean with pH
neutral cleaning cloths (Latex gloves were worn) and exposed to
bright sunlight for several days, upon which the mildew disappeared,
but upon removal from the sunlight, the film redevelops.

Being of 1942 manufacture, it is assumed to be chrome tanned
leather.  It is the property of a local museum where I am a
volunteer. It is to go on display with other World War II artifacts
and equipment.
