This is one of a number of items that have been made by a local craftsperson and are sold in the Blackdog Antiques centre in Halesworth, Suffolk, UK. A great shop and some very beautiful items, well worth a visit.
The gift to farmers across East Anglia, solidly built Nissen huts.
Here's a link to the official website that details their history.
