I'm trying to figure out where a Lucille I have was made. It has an August 2000 serial number but no f-holes, so no "standard orange label". The online Gibson serial database says Kalamazoo based on the serial -- which is obviously wrong -- but because it doesn't come up as Memphis makes me think it's from Nashville. Which then got me wondering when they moved Lucille manufacturing to Memphis.

I'm interested to know the exact date that Gibson ES guitars stopped being manufactured in Nashville prior to the move to Memphis. I believe it was some time in 2000, but does anyone know the exact date? (and/or if there was any change in serial numbering such that you could tell if a guitar made that year was from Nashville or Memphis.) Thanks!
