Thanks Tim, but it’s not quite, the y and u particularly are different.

Oops you are right, I had rejected VAG Rounded but that has the y and u that you are looking for, however, the a is single storey and the B and D don’t match but looking at your scan again I wonder if the B and D (especially the D) had been condensed. The a looks out of step with the rest of the logo.

Thanks for your time Tim, I can probably manage the BDS (I think it may have some roots in DIN, or something related), its really just the l/c copy I’m struggling with.
