I will check for sure tomorrow but I am assuming just like Christopher stated in a different thread..
I am assuming that the limited edition refers to a special backstamp on the bottom of the piece (as most exclusive LLOMs) and similar to that of the Thomas Point Screwpile LLOM piece offered in 2007 which was released under the old number of LL129 instead of a "new" LLOM product numbers.
In the case of the Thomas Point the screwpile's on the re-release, for Bill's signing at the Calvert Marine Museum and the Maryland Challege, plus Bill's trip out to Thomas Point, were longer than the original. The paint job was a little different, also.
The following is a thread that I posted comparison images of the different Thomas Point LLOM in 2007.
