Lincoln Zephyrweight Suitcase

A fair sized suitcase this was made by Lincoln and was part of the Zephyrweight line. Not exactly sure how much a zephyr weights but I am thinking that is supposed to be light weight.
Using my handy folding ruler it is 21" x 18" x 8 1/2".
This has attractive contrast stitching on it along with metal fasteners and some reinforcing pieces.
Also some airline tags on it mostly United. The suitcase looks fairly old and may have ridden in a DC3. More likely some early jet age action.
