I haven't found anyone who remembers from the late 1950s a confectionery known as an Americo Bar. I used to buy one quite often in Harrow at a small sweet shop. It was a chocolate covered bar which had nougat inside and possibly nuts but no wafer or biscuit. It wasn't to my knowledge made by the leading makers of the time Rowntree, Frys, Cadbury etc. The year would have been approximately 1959/60. Does anyone else remember it?
