Not sure if I can help you out or not but please try contact L.David Keith at Grey Ghost Safaris.
He is a long time booking agent (and a good friend of mine) and I might be thinking that an outfitter that he represents from the Eastern Cape may have some of these, or they may be the Sth American variety, not sure.
I don't have L.D.K's contact details with me but can find them for you if you need. You can p.m me for contact details if you wish.
Not sure if i'm 100% accurate with my advice but it's worth a try.
I hunted with Simon Kyle Little of Australian Big Game Safaris in the Northern Territories. I will recommend him without reservation. He is a true hunter. There is a nice wind that kicks up as a sea breeze about 10 AM everyday. I shot a bull at 18 yds with him. I went on a management hunt and ended up negotiating for 3 bulls. I shot one with my bow, one with his double and a monster with his .375 that tried to kill us. What an awesome trip. I used Easton dangerous game arrows and Ashby 325 gr 2 blade broad heads with a 80lb hoyt Vectrix. I Shot one bull and 3 cows, all complete pass throughs with this combo. My buddy shot one bull and 2 cows with same broad head, 80lb bowtech. same result

Hi Bob, how's things going in Wyong?. Down your way a couple of years back but haven't been in NSW since Ebor for the fishing. just getting over some nasty storms up here in Qld, seeing the sun for the first time in a few days. I'm going to NZ in the spring and hope to clean up a few buns while there and perhaps shake the spiders out of my old .303LE (currently owned by my BIL). Cheers Brian
