In the earliest days of the Saharan gold rush of NWA meteorites (late 1990's), large numbers of meteorites began to flow out of the Saharan desert. Many of these early meteorites were common weathered chondrites (OC's), and they created logjam in the classification system (which was more limited at that time). Some prolific importers of NWA meteorites were allocated single NWA numbers for provisional classifications, or had blocs of numbers reserved them for them in the NWA catalog. Over the many years since then, these early provisional classifications have been lost or forgotten in the system. There is little chance that many (if any) of them will be finally approved and published in the Met Bulletin. These early meteorites are now a relic and oddity for collectors and they are not commonly seen on the market.
This particular stone, NWA 285, was purchased by Dean Bessey in Morocco. The stone's stated origin is Algeria in the year 2000. It is an ordinary chondrite and the classification was never finalized.
