How about Helvetica Rounded Bold Condensed?

I have to agree, now that I look at it closer. Sigh!

And AG Book Rounded is similar -- too 'balloonish'.

I actually once saw an old Letraset catalogue that had a rounded DIN typeface in it. Funny stuff.
Just thought I'd mention this. If I'm really lucky I can get hold of a scan from the catalogue someday.

How about Macarena DT Bold, perhaps a bit condensed?

I was also wondering what it was when I saw it , as it is very similar to Chevin, (Din-like proportions, but straight-sided curved characters, CDGOQ, and rounded), but not so totally monolinear.

I'd be interested to find out too!
