The original and most prevalent style, like the Downing Street sign sent to auction
It was used for signs produced for about a century from 1836;
there were many detailed variations in that time
The next street, before and after pictures when I repainted the sign in 1972
The same style, a restored sign not (so far at least) remounted; 20th Century
The same style again, next street to Downing Street;
probably early 19th century like the sign offered for auction
The sign that was offered on ebay, recovered and (as can clearly be seen) remounted;
20th Century
The remaining cast iron sign in Downing Street. A later style, with detailed font changes
Another cast iron style, smaller size letters, including initial letters
Another style, using individual letter tiles. Included because Downing Street once had a similar
sign. Aficionados of typography can see why individual tiles like this don't look so good.
