Being a former employee of Lane Masters at the time these were made, I would like to clear up a few things about the Conquerer.
First thing, is if there were identical number, which I saw happen on a few occasions, it was because when production ended one day and they started the next, sometimes they would forget to "advance" the serial number in the engraving machine, thus creating the duplicate number. The weight is irrelevant to this, as the balls were not done by batches of weight. being that the numbers and serial numbers were always changed manually, it is even possible for the balls in question to have the same Limited edition number, but different ball serial numbers.
Next, is the fact that there were not even 500 made. That was the round number to market, but in reality the cores were leftovers from a bad batch of AP2's that cured too hard. The number of cores and/or weights available was completely random. I believe the actual number was around the 425 - 450 range. This also explains why there was a high amount of 14lb and 16lb balls, compared to 15 lbers. It was simply because the cores weren't "produced" to be a new run of balls.
To salvage the materials of these balls, we had the idea to cut them down to an inner core size, and reshell them. Look inside and you will see AP2 blue as the "filler" color. This made the filler actual urethane (not the traditional filler material) and of a harder durometer than the outside cover.
