Just got an original Steyr AUG 14" (13.8") barrel, it is brand new, only 90 rounds fired through it by the original owner, and then put away for 30+ years!
I wanted to compare it to the new 14.5" barrels, so here are two quick pictures- the difference is immediately evident and I will try to get more pics of the differences in the near future.
Enjoy!

AUG 14.5" 20203 production barrel top (with A2 flash hider installed by me), 1990's AUG 13.8" barrel below. grips on both are fixed in place and will not fold.
AUG 14.5" barrel with A2 flash hider (left) is still a bit longer than AUG 13.8" with closed tulip device (right). The 13.8" barrel is chrome lined and also has different markings on it. The gas cylinder plug looks like bead blasted stainless with a more matte finish to it compared to the current silvery 14.5" plug.
