The Ever Ready Sky Casket is a mid-1950s British battery portable valve radio, built to look like a small jewellery box or treasure chest rather than a conventional wireless.
It was made by Ever Ready Co. (GB) Ltd. in London (and later associated with their Poole works). Sources list it around 1955–1957. The export equivalent was the BEREC Harlequin.
It sat at the luxury end of Ever Ready’s “Sky” range: wooden case, cloth covering, gilt fittings, speaker hidden in the lid, ferrite-rod aerial inside. Original price was about £14 10s 10d to £15 plus purchase tax — a lot when average weekly wages were around £7 10s.

Why it looks like a casket
Closed, it resembles a small jewellery case with a clasp and carry handle. Open the lid and the control panel appears: volume on the left, circular tuning scale in the centre, wavechange (Long / Off / Medium) on the right. The elliptical speaker is inverted and mounted in the lid so the set stays slim. A brass contact was wired so the radio would howl if you closed the lid while it was still switched on — a simple reminder not to flatten the expensive combined HT/LT battery.
