ST. John the Evangelist Bollards...

What a pair of Bollards...

We are outside Palace Wharf on Rainville Road W6 where I came across two bollards with a portcullis and ST. John the Evangelist marked upon them.
It is plain to see that these bollards are not part of the original Palace Wharf design and are more likely salvaged from a church/parish in central London close to parliament which would account for the portcullis marking on the pair of them.
If we look at some records we find that ST. John the Evangelist was in fact ST. John, Smith Square SW1 created in 1728 and bombed in 1941 rebuilt and is now a popular concert hall. Could these bollards have found themselves salvaged from the bombing or the rebuilding and made their way to W6 ?
If we take a look at the bollards (below) we see they stand upon a sturdy base with a circular body that rises vertically with three ridged areas on the main body and the half ball shaped top.
I bumped into an interesting chap/artist who actually works in this splendid building (see bottom picture) and please do click on the following link ACAVA to see riverside images of the building and the work he and other artists do.
