strange hallmark help please (photos now added) ****

I have recently started to collect silver, I came across this letter opener, it is 5 inches long and has the words St Johns Coll. engraved on the blade, It is in the shape of a sword The hallmarks are a mystery to me, they do not look like any I have yet studied, I.E do not look British circa 1850-2008
They most likely are continental or even Asian but I really don’t know, perhaps some one can help, the photos not the best but I have some more if it will help.
Many thanks in advance
