NHER 9110 (Building record) - Little Ellingham Hall and clock tower

Listing 1983 (S1) describes clock tower and two cottages, 1855. Gault brick with red brick dressings and slate roofs. Cruciform plan, central clock tower. Cottages two storeys in form of four gabled wings with partly external end stacks. Two round arched windows each storey with projecting keystones. Two hipped porches in south and west diagonals with round arched openings. Square tower of three stages with clock face to east, balanced by blank roundels to other sides. Heavy brick cornice supports domed timber cupola.
The hall itself is not listed.
(S2) dates the hall to 1855, or rather says (S3) does so, and queries if that can be the date of the tower. Otherwise description the same except that he refers to four rather than two cottages.
Does the listing have definite evidence to date tower also to 1855?
Grid reference is that of hall as maked on 6 inch Ordnance Survey map (S4), but not clear if the tower is the building marked at TM 0030 9944.
Needs visiting, and to assess if hall is worth numbering as well as tower.
