3ttt made 26.0 bars. Cinelli made 26.4 bars. I think it was the late 80's before Cinelli made 26.0 bars. I think to find 26.4 bars you will need to find Cinelli bars. There are plenty out there.

The only picture I have at the moment of the Cinelli leather wrapped bars is from a distance when they were on my wife's bike. I'll try to snap some proper pics tomorrow in the daylight.
