Re: Screen magnifiers - 40s/50s TVs
OK, solved it. Liquid paraffin is listed in the British Pharmacopea and is available off the shelf at my local pharmacy in 150ml bottles. The pharmacist can also supply a 2 litre size for about £10.00, 25 litres available too.
My grateful thanks to all who have added their illuminating contributions to this discussion.
Magnificently,
Dave
