Since writing to you about this, I remembered that the 'warning' I had
in my head came from David Springett who said that rotten pewter was
pewter which had too much tin in it, and that a bad bobbin could damage
a good one.

Although pewter degradation is often talked of in "Human" terms, I am
pretty sure it is not catching! It is a chemical process that starts
when the pewter gets to certain temperature (I wrote an article about
it many years ago but I have forgotten the details!... old age!)
I do remember the story that says that Napoleons army uniforms had
pewter buttons and when the went to Russia in the freezing conditions
there, the buttons disintegrated.

Brian, I've got the "warning" in my head that if we have a "rotten"
pewter bobbin, we should always keep it separate from any other
pewter bobbins as they can contaminate the good pewter. Thoughts?

The one warning that I would make is regarding bobbins that have
pewter in them. They must not be kept in any place where they might
get very cold. If they do this will accelerate the process of pewter
degradation.
For other bobbins, keep out of direct sunlight.
Avoid damp
Even temperature
