There are 3 boxes of this type in Cornwall: Lostwithiel, Roskear and St Erth. The ignorant oafs at English heritage have listed Lostwithiel, which has ugly modern windows and a porch which dates from 1923 and does not fit, while Roskear and St Erth, both well looked after and beautifully restored to original appearance, are unlisted.

Many thanks to you Roy.
