The specs of the new "classic" Stewardess Bag 17996 are still up at Net-a-Porter. This is what they show, and yes, the strap is a lot shorter:
Width 11" / 28cm
Height 11" / 29cm
Depth 4" / 11cm
Handle Drop 14" / 36cm

But like the others have said, the seller always needs to show the bag she's actually selling.
If you're looking for the heavy vintage Coach leather, the new "classics" are NOT the styles to buy - a lot of posters have been disappointed in the leather quality too.

Thanks, Hyacinth! After reading the thread that BB referenced above, I see now that this is one of the re-issues - not a real Coach Classic.
