Depersonalising this, how common an occurrence is this? And how 
common these days? And what causes it?

I too was a little surprised by the strength of response from my old 
Canterbury friends to my innocent enquiry. I am sure that porosity in 
modern bells is equally as interesting and appropriate a discussion 
as the colour of L&J's nuts... :)
