Make and model.

It seems to be by Ei Electronics of Shannon in Ireland, though the
manual also gives contact details for Aico Ltd in Oswestry.

The model is Ei141RC.

The (strongly) recommended battery a Duracell MN1604 Energizer 9 V.




They are called Ei because they are made in the Emerald Isles
