Stu, what does CPR use for the colour baseline for the repro PFs? I would assume that using a NOS PF, even if stored away from light, over the 30+ years will have colour shift. Looking at the images for Fathom on ipdb.org, the back of the flyer gives an indication of what the colours did look like. Hard to say whether looking at the image on my screen of the flyer is true to what the colours actually looked like back in 1981. But what is for sure is the the colours in the flyer are very different to the NOS one shown in this thread.

So if CPR had a NOS Fathom PF to begin with (and not sure if that is what you use to baseline the colour), how does CPR set the baseline of the colours? Thanks.
