I'm cleaning out my gel drawers and finding some un-identifiable color. So for you history buffs, help! 1.) I know that one is a Roscolux colored diffusion of the R120 range, but in Sky Blue, that's been discontinued. (the student who wanted 2 cuts, cut off the label!! I seem to recall R128?) Was this really a thing? 2.) Some similar Sky Blue frost, but more akin to Lee224: heavier frost, not coated-on-one-side. Similar to R64 or R67 in color, paler than L224. It was grease pencil labeled "G108" which is NOT GAMcolor or Gelatran, and probably meaningless. 3.) Two folders of cuts labeled G058 and G053. The G058 folder is also labeled "aka G850," (and it is!). But what is the G053. I got frustrated that those few cuts were unidentifiable, so I pitched the whole folder, but I'm still curious about the numbering system; a thought was maybe Gelatran, but there isn't a 058 and 053 is green, not blue. Any old-timers remember any of this stuff?
