Had this bottle label Jpeg emailed to me some time ago. It was made by Newport brewers Lloyd and Yorath and the date perforated on it is 16:6:37. Lloyds were based in the town centre on Cambrian Road, the brewery was taken over by Birmingham-based Ansells Brewery in 1951 and was closed in 1961. The buildings were demolished shortly afterwards and the site remained empty for years, used as an open-air car park, until the Cambrian Retail Centre was built on the site.
Luncheon Stout does have a rather civilised name to it. Although in the Nanny State of the twenty-first century it is doubtfull if any brewer would get away with promoting beer as a lunchtime drink.
