It has certainly got that distinctive mid-20th century look, with the clock sized around 67cm across and those 'rays' mounted on gilt metal spikes.
The seller says it is in 'good working order' and 'keeps good time,' with a single AA battery powering it (the mechanism may have been changed in the past). The only blemish is 'some minor loss of gilt' to some of the spikes. See the listing for close-ups of that.
