There is a Mudcat thread HERE which tended to debunk that definition of Brass Monkey - post any further discussion on that topic there.

Two pubs in the Plumstead/Bexleyheath area were known by the ladies who had owned them in my parents' day.

"The White Horse" Wickham Lane was known as "The Fanny on the Hill". When it was rebuilt twenty odd years ago, the name was included on the sign, but I think it has been dropped now.

"The Royal Oak", Mount Rd, Bexleyheath, still has a small sign proclaiming it as "The Polly Cleanstairs" - my mother told me that the original landlady had been a skivvy until she came into some money.
