Can anyone identify this chocolate bar?

Factual Questions
1

I remember a chocolate bar that came out in the early 1970s…it had a red, white and blue wrapper and had three layers – milk chocolate on top, dark chocolate on bottom, and a thin white layer (I don’t know what) in between.

What was this bar called? Who made it? And why don’t they make it anymore? It was the best chocolate bar EVER! (If you ever ate one, you would know.)

Sounds like it could be a Trio, made by Nestle, I think.

Trio is a biscuit isn’t it?

Cadburys still make a bar like that, but I can’t remember the name; I’ve only ever seen it on sale in Ireland.

Droste make stuff like that too.

I remember it, I tried to separate the layers when I was young. I don’t remember the name, tho. Sorry

Could it be a Caravan bar??
