Alice was driving the family Rolls Royce and was giving Brenda a lift. As Brenda got into the car she found two golf tees on the passenger seat. Not recognising them, she asked "what are these"? Alice replied, "they are for my husband to rest his balls on when he is driving". Brenda responded, "gosh, Rolls Royce think of everything".
 
In similar vein, if Brenda asked what the thing shown below is, Alice would reply: "it is for the Lord Mayor of London to rest his sword on when he is praying".

See this description of sword rests. This specimen is in the Church of St Clement Eastcheap. It is still in place in this photograph (on the left) and in this photograph (on the right) but every year since 1998 we have removed it before our mystery play performances so that it does not obstruct the audience's view. See also a few sword rests still in situ including the one in Southark Cathedral above. Just above the City shield is an horizontal ring. The tip of the sword is inserted upwards through this ring, then the handle is rested on the dished plate at the bottom.

Below the City shield is a coat of arms which bears the motto "Strike Dakin strike". Asking Google about the motto, we find Kelly's Directory for Derbyshire, 1891 which tells us that in St Peter's Church Fairfield there is a mural tablet to William Dakin, a merchant of London (1848) with the singular motto of that family, "Strike, Dakin, strike; the Devil's in the Hemp". (Here the punctuation gives an indication of who is supposed to be striking whom!) The church's website does not mention the tablet but tells of two other Dakins in the graveyard.
 
In fact the rest was probably presented to the church by Thomas Dakin (1808-1889) who was a Lord Mayor. This page (cached copy) on Deakins of Australia and England gives a good explanation of what the motto means.
 
Another Google hit comes from an unlikely source: small town Minnesota, in this article (cached copy) from the Kanabec County Times about someone being busted with $1000 dollars worth of pot [= Cannabis = hemp]. It definitely must be small town because the story has generated forty eight comments! One of these (search text for Dakin) is from someone who still has the family motto word perfect after seven generations.
