Thank you! There were at least 3 and probably 4 colors on the blue saws. Early XL--12s and Super XLs, then later XL-12s. Super XLs, XL-700, XL-901, 150s, XL-101 and XL-102s were slightly darker. Then later on there was a Super XL Special Edition and Old Blue that were different from one another as well. There are two Pontiac, blues when mixed match the late 60s blue saws, but you need to use one in none metallic finish to match it perfect. I have worked with colors for over 30 years.
