I recently acquired three stones of 252g, 57.6g and 6.8g confirmed as a pairing of the NWA 2990 (an olivine-phyric shergottite), the NWA 5960 and NWA 6234. Still waiting for the NWA number for these three stones in the form of NWA 1XXXX.
Information from the Meteoritical Bulletin about the NWA 2990:
