Wilkes serial number 15510 was the first of a small run of O/U guns made. I do not know how many in total. That would have been in 2002; they closed up the shop in London in 2003.
In March 2012 Greenes Guns, Virgina were selling one, no serial number given. They claimed it was one of 10 made. Here is their description:
