In search of a particular brick

[Retroshift]

Hi, I am looking for a brick that is the bigger brother of this one (brick 33243 - Brick, Modified 1 x 3 x 2 with Curved Top). I thought there was one in the format of 1 x 6 x 5, but I can't find it anywhere. Does it exist?

Do you mean this:

No, it should be curved actually. I mean the full version of part 6060 . I really thought to have seen it somewhere. Or is it duplo or something?

I don't think I've ever seen such a piece. I'm not too familiar with current Duplo pieces, but if you've seen a part like this before then it could have been Duplo. I don't know of any System pieces that meet your description though.
