I've seen pics of that color.The GL2 with baby blue finish is one of my "if I win the lottery" guitars.
I still regret not buying it the day I saw it hanging on the wall at Manny's all those years ago...
I've read that about 95% of all L Series production was black. Of the remaining 5%, almost all were white. There were only a handful of them made with actual colored gel coats, mostly one-offs, and a few that were painted. Then there's the Reeves Gabrels chrome GL, and the much more playable one David Bowie ordered after seeing Reeves' guitar. If you had that light blue L it would be like having a Model T with factory shell pink paint.
