I learned to ring in 1972 and have been a member of Wymondham Abbey tower since 1975. For all that time the band has had more women than men on the 'books' and it is always encouraged that everyone rings everywhere in this 10 bell, 26cwt tower. Most ringing is mixed - as one might expect - but an all male band is likely to cause comment as it is far more unusual than an all, or predominately, female one.
In the local Branch I can think back to several women chairmen and ringing masters. Gender has not seemed significant. I have no problem with the term chairman having been one myself in non-ringing roles for several organisations. I feel it is not a gender-specific title as secretary is not. The same applies to Ringing Master which is an historic title in many towers and it would be a pity to see it discredited.
So although reading your research is of interest, and food for thought, the role of women in ringing in the last, say, fifty years is not something I find to be in need of highlighting.
As the saying goes, perhaps we Du Different in Norfolk :-)
