Acronym

[Frank W]

An 1861 Census entry records an occupation as
"Clerk - Admiralty K.P.S. for Westminster"

What does K.P.S. stand for?

Edit: Zooming-in shows that the "K" may be a crossed-out "V" and is not immediately followed by a full-stop
Census ref is RG9-778 Folio 67 P 10 Sched 48

I think the 'K' is in fact an ampersand and it reads '& P.S.', which could stand for Private Secretary, or perhaps Parliamentary Secretary
