Hi Lew...Hi Douglas,
seems to be mainly the UK eBay 'market-place' that regular listings state Zulu for practically anything thats African. Doug we could start a wholesale business in Zulu spears....you send them in bulk, I'll bury them in the garden for a few weeks.....dig them up...then post on eBay as 'Rooke's Drift' bring backs ....sorted.....we'll make a killing (pun intended)
