Identifying Vintage Double Turnlock Briefcases - Brief, Diplomat, and Prescott

These vintage Coach brief bags get confused quite often, but there are differences in the colors released, number of pockets, straps (if any), and even small differences in the sizes. First up is the Brief Bag style no 5080 Gussetted pockets on the outside, zippered compartment inside The 6 colors released were Mocha, British Tan, Black, Red, Burgundy, and Tabac Dimensions - 16"W x 11"H x 2" Next up is the Diplomat Briefcase style no 5170 Gussetted for extra large carrying capacity Interior divided into two sections Leather-lined flap with two flat pockets underneath to hold colds, arline tickets, travel documents, calculators and pens More pockets inside The 5 colors released were Black, British Tan, Burgundy, Mocha, and Tabac Dimensions - 16 1/2"W x 11"H x 2 3/4"D Finally we get to the Prescott Brief style no 5275 The immediate noticable difference with this bag is the shoulder strap Full outside back pocket, two front gussetted pockets with business card pocket and two pen holders under the leather-lined flap Inside zipper pocket 46" Adjustable strap that detaches, with a shoulder pad that detaches The 3 colors released were Mahogany, Black, and British tan Dimensions - 16"W x 10 1/2"H x 3 1/2"D I will be listing a Prescott Brief soon, and since a list of listers think that any Coach brief is the Diplomat version, I wanted to share these catalogue scans so the differences could be known.
