Trunks are differentiated from chests by their more rugged construction due to their intended use as luggage, instead of the latter's pure storage.
Later coverings include paper, canvas, plain or embossed tin, with an uncounted assortment of hardware and hardwood slats to keep it all down.
The use of classic trunks for luggage was widespread through the first two decades of the twentieth century but began to fade in popularity thereafter in favor of the modern suitcase.
There were hundreds of trunk manufacturers in the United States and a few of the larger and well known companies were Rhino Trunk & Case, C. A. Taylor, Haskell Brothers, Martin Maier, Romadka Bros., Goldsmith & Son, Crouch & Fitzgerald, M. M. Secor, Winship, Hartmann, Belber, Oshkosh, Seward, and Leatheroid.
The easiest way for the casual observer to date any trunk is still by examining its style, so a short description of each aforementioned major variety follows.
Jenny Lind trunks have a distinctive hour glass or keyhole shape when viewed from the side.
The most readily recognizable feature of Saratogas are their myriad (and generally very complex) compartments, trays, and heavy duty hardware.
Earlier examples usually included labor-intensive hardwood slats that were curved with the top, while there was a revival much later with rarer, all-metal ones being constructed.
They are distinguished by either their flat or slightly curved tops and were usually covered in canvas, leather or patterned paper and about 14 inches (36 cm) tall to accommodate steamship luggage regulations.
Most were built with flat tops and had inner tray compartments to store the owner's valuables deemed too precious to keep stowed away in the baggage (luggage) car or ship's hold.
Barrel-staves are sometimes referred to as a form of dome-top trunk, but generally date from a decade or more earlier and are notable for having horizontal slats instead of vertical, giving it a distinctive look and construction.
They are characterized by a distinct trapezoidal shape when viewed from the side, although the earlier period tended to have a much shorter flattened top section than the later did.
Many of the better wardrobe lines also included buckles/tie-downs for shoes, removable suitcases/briefcases, privacy curtains, mirrors, make-up boxes, and just about anything else imaginable.
During the steamer trunk restoration process when the inside paper covering is removed, dated notes in lead pencil made by the original craftsman may be found, as well as the circular saw blade impressions made on the rough-cut wood at the saw mill, both of which give added character and value to the restored trunk.
