Thanks, John (for not bidding :-)). I've posted add'l photos to the Kuba horn folder showing what I think is an interesting melange of both Lulua and Kuba curvo-linear motifs:
In addition to the "y" design, the ribbed markings towards the top of the neck, to me, appear similar to the ribbed neck scarification I've seen in old photos/drawings of the Lulua (also seen at the front of the neck on many Lulua figures--between the "scaling" patterns on the sides and back). The bottom of the horn shows a more typical interweaving Kuba skein pattern, which you can see well in the close up.
Another member was kind enough to send me contact info for the former curator of the museum, to whom I sent an email to see if I can confirm its provenence and get any more info. I'll pass along any interesting info that I'm able to obtain.
I thought I should add a note of caution about Ebay to any new collectors out there. While one can occasionally find a quality piece for sale, 99% of what is sold through Ebay is fake (and most poorly rendered at that). Many are from the carving markets in Cameroon and other countries that churn out bad copies of pieces from catalogs and museums). Even for someone with a trained eye, a stylistically correct piece with a nice apparant patina and suggested provenence from a reputable seller, it's a risky venture to acquire pieces this way. As such, I wouldn't suggest Ebay to anyone that wants "real" pieces of high value (asking prices on Ebay are not indicative of authenticity in any way, nor is positive feedback for a seller necessarily an indication that what they are selling is not fake). That doesn't mean there aren't a few pieces that occasionally become available, but they are the proverbial needles in the haystack of crap.
