I visited this St Mary's "en route" to my holiday near Cambridge. (Are you impressed with my language skills? I am!). Wansford is currently in Cambridgeshire but it has moved about a bit [the north half of the village - containing the church - was in Northamptonshire and the south side in Huntingdonshire, Big Ted]. The church has a lovely purply-red sign though.
I went inside to check out the church; it's a lot smaller on the inside than on the outside. But it has a lovely old font built around 1100, so I made sure to have my photo taken on it.
