Can anyone tell me when the RNR established a branch in Brighton/Hove?

There is a RNR Battery recorded as being in Hove, and in use by the Royal Naval Artillery Volunteers (presumably from 1874) when they came into being.  The  Sussex Division RNR was based in Newhaven from 1859 when the force was formed so the time scale would appear to be sometime between 1859 and 1874.

Any ideas anyone?

February 14th 1874. Letter to the Editor of the Brighton Herald from Arthur Sutherland,asking for names to be sent in to form a Brighton Battery, in particular from members of the Brighton Rowing Club,  drills to consist of "great gun, rifle, pistol and cutlass exercises". May 2nd 50 names having been forwarded, a Brighton Battery was sanctioned. June 29th Sussex Corps formed. The offical date of the founding of the Sussex Division.
