Check out this link which I find to be very suspicious: http://cgi.ebay.com/Kubicki-Ex-Fact...oryZ4713QQssPageNameZWDVWQQrdZ1QQcmdZViewItem No serial number on the neck. Seller says there is one in the neck pocket but doesn't want to disassemble the bass to check because he just restrung it. Seller say in his recollection, this is number 56 and all Phil could tell him about the bass is that it was made in the mid 1980's. Here's the thing-- first, the SN would be 056 and not simply 56. Second, if this bass was number 056, or anything less than #100 or so for that matter, the electronics guard would not be shaped like a semi-circle. Rather, it would be shaped like a semi-circle plus a slight additional tail where the bass was routed all the way to the output jack. This bass does not have that feature. It is only routed out like a half circle. Third, the hardware on the back has print regarding patents, etc. Early Kubicki's did not have this-- they were simply blank. Fourth, there are no closeups of the bridge. While I do not want to be too harsh about this seller, I would sugest that it is really easy to distinguish the difference between a Philip Kubicki-made factor and a Fender-made factor based on the bridge. The fenders look cheaper and tend to scratch a lot as they were not anodized black but rather were painted. Lastly, the opening and BIN prices are at the high for Kubicki's on ebay-- in fact they are at the very high or above. While such prices would be warranted for a really old Kubicki, I would make such a disclaimer and provide evidence (i.e. neck pocket photos) to support my prices. Neither hs been done in the case of this auction. I'd love to get other TB-ers observations and thoughts about this. Either way, buyer beware!
