A featherweight has a little lift up extension flap to the left of the needle, and only weighs about 11 pounds. Your 99 would be heavier than that, but nice to have, all the same.
If the case was damaged in transit, don't you have a way of getting some compensation for that from the carriers? No harm in trying.
This is a pic of a Featherweight, with the extension flap hinge clearly visible
