More important it is active cell rot that can spread to other razors or steel in proximity. The problem with the Marble type scales is companies were using different formulations to get the effects and they rot at varying rates. Sometimes you get lucky if caught early and just removing the razor from the conditions that caused it to kick off will stop or slow the reaction.

But they are timebombs and you never know when they will start again. The pinning indicate they probably are not original. I would not store it with the rest of your collection, It is too bad, some of those scales were spectacular, and as far as I know no-one makes anything close.

I unpin them and rescale, though I do have a pristine Craftsman,(Notorious for Cell Rot) in original scales that showed minor signs of rot when I bought it years ago, but have not reoccurred. It is stored separate from other razors.
Always a good reminder about cell rot. So far I've been lucky with the swirls and I keep a close eye on them. I might be playing with a bit of fire, but I just really like those patterns. If they start to kick off, I'll have them out asap and look for some modern materials to re-scale with. Until then, I'm going to enjoy them as much as I can.
