I don't know all the details, but after FMIC closed the Guild factory in Westerly, RI in 2001 and moved production to its plant in Corona, CA, the first Bluesbirds made there were done by the Fender Custom Shop. I had one awhile back with the holoflake finish.
I'm not sure how many Bluesbirds were built by the Custom Shop. Most, if not all, were built with an unbound dot fretboard. Fairly quickly, the model was transitioned to normal production and returned to the bound fretboard with block inlays as had been done on the Bluesbirds built previously at Westerly.
Until they stopped building them altogether circa 2004.
