If historical posts are to be believed, there is only one original source for the BB10 which is an unknown but considered high quality cultivar and that is Dan. Dan had discovered the plant which was likely either a sport / mutation of a known or unknown variety or the result of natural pollination / cross between two naturally occurring figs in the discovery area. Regardless, the BB10, as it was named, was, according to his own assessment, above and beyond in terms of quality. How the BB10 came out of Dan's private holding and into wider distribution is unknown but once the genie was out of the bottle several more folks acquired it. One of those second line folks then made it available to others and became the common source for the plants and cuttings now finally being made available to other enthusiasts on ebay. The current offerings on ebay are by Wills from OurFigs and by Dave who is a member here and on OurFigs. Both are highly respected and trustworthy sources of figs and there are not many that would dispute the authenticity of the figs that they are providing on ebay. There are a few others that also have the BB10, including "pukzpukz" who is a member of both fig forums as well as on Rafed's FB and who recently posted that he will be doing a benefit auction for a BB10 plant from his own inventory in late winter as well as making cuttings available some time after that. I believe that Pukzpukz also posted that his source for the BB10 was the same as the others. Pukzpukz also frequently sells figs and other plants on ebay and is very involved in the LSU fig research and development program; I believe that all of the LSU varieties, either formally released or still under review are his specialty. In any case, those are the three sources of BB10 that I am aware of; I am one of the actively engaged and interested bidders on ebay for this variety as I have no qualms about the authenticity of the cultivar and consider the sellers to be of the highest order and trust worthiness. There are F4F members who sell varieties on ebay, including BM, whose names are synonymous with value, integrity, quality and generosity; we all know who they are and we look forward to their auctions and bid on their inventory without concern, I personally have bought quite a bit from them myself, these BB10 sellers are on the same order as far as I am concerned.
