I was watching an old Late Night with David Letterman on Youtube the other night and saw BB King admit that there had been "many, many" a 'Lucille' throughout his career. In other words, he stuck with the moniker and gave it every subsequent #1.
Brilliant bit of branding, as everyone in his day knew of "Lucille." And of course changing up or replacing instruments is not something the casual punter gives much thought to in any case, so no need to throw a spotlight on such details unless a snarky David Letterman asks a gauche question.

Lucille's beginnings date to 1949, when King, then in his early 20s, was performing at a nightclub in Twist, Arkansas, in the dead of winter. To heat the cold room, King recalled, "they would take something that looked like a big garbage pail, half fill it with kerosene, light that fuel [and] set it in the middle of the dance floor." All well and good, but on this night, a fight broke out between two men, and the pail was knocked over. "It spilled on the floor, it looked like a river fire," the guitarist said. "And everyone started to run for the front door, including B.B. King."
The blueseman managed to make it to safety outside — only to realize he had left his guitar behind. He raced back inside to retrieve it even as the wooden building, he said, "started to fall in around me." The next day, he learned that two men had died in the blaze and that the fight that had set off the tragic chain of events had been over a woman who worked at the club. Her name was Lucille.
The original Lucille — the guitar King rescued that night in the fire — was an inexpensive, small-bodied Gibson L-30 archtop. The singer would go on to play a range of guitars over the ensuing years, attaching the Lucille name to each one. He was particularly drawn to Gibsons of the semi-hollow "ES" (Electric Spanish) variety, such as the ES-335 model that can be heard on his legendary 1965 disc, Live at the Regal. He eventually arrived at the ES-355, a top-of-the-line model boasting stately looks (gold-plated hardware, multi-layered binding, big mother-of-pearl fretboard markers) and a sharp but sweet tone bolstered by dual humbucking pickups and stereo and mono outputs.
