Now there's a thing!
Just seen it on p.42 of the doyouremember wrappers thread, and IIRC was first available around 1984-ish. I think it was in the form of two fingers joined together.
I did a paper round at the time, and the Indian guy who owned the shop always had a wide range of confectionery products - many of which you never saw in the chain outlets.
This was one of them I'm pretty sure, and it was seriously good.
