I had a 133 series StingRay about 15 years ago. Bought it new for £999 from Nevada music iirc. The choices were Black, Candy Apple Red and Pearl Blue. I got black with rosewood.
They were advertised at the time as these three colours only but with the choice of a maple or rosewood fretboard. As said before they were all 2EQ and came with a gig bag.
The '133 series' reference never came into the conversation until discussion on the EBMM forum used this nomenclature on account of it being part of the build number
