Here are the specs as related by the seller to me:
"Howard Hill Archery Limited Edition "Sirocco" offered in 2009. I am the second owner. Only 50 "Siroccos" were built. This one is #48. The bow is 66" tip to tip, 48lbs @ 29", so probably right around 45@28. It is right handed. The limbs are a straight profile, no backset or string follow. The handle has a locator grip as you can see in the photos below. The bow features a teak riser. The riser handle is wrapped in black genuine stingray skin. This is the only time stingray has been offered by HHA. Really comfortable in the hand and nice and grippy. The riser has a sterling silver marlin inlay. There are five laminations to the limbs under glass. From back to belly the lams are as follows: black glass, 2 lams of bamboo, 1 center lam of cocobolo, 2 lams of bamboo, clear glass. The limb tips have double overlays of whale baleen over bamboo. On my bow the belly lam of bamboo, the one under the clear glass, is dramatically darker than the inner bamboo lams, so I think it is tempered. I've never handled another Sirocco, so I can't confirm that. "
The grip IS grippy! I like it - especially in this heat - it doesn't get slick! Great idea for a handle material, tho' I haven't seen it elsewhere. I'm enjoying the bow (it's a better shot than I am). Thanks Mudd for posting the pics!
