Help! Its driving Me Mad!

I have a lovely almost full vintage teaset and really would love to track down more.  Thing is, although I know from the marks that its Collingwood Bros, I cannot identify the pattern, so don't know what to search for. Do any of you clever china experts have any light to shed on it.  I wondered if it was called `Hampton` as it says it on the mark, but have found no evidence to suggest it is.
