The BURROUGHS is featured in my article contained in the December 2006 ETCetera.  You can consult that magazine for complete coverage of the history and design; here are some supplemental photos and pieces of information.
Two Burroughs machines are in our collection here; the one at left is that mentioned in the ETCetera article.  Another one, seen below, differs in that it is fitted with a six-key decimal tabulator.  Machine on the left is serial number 51A 80724; the machine below is 51A 261068.  The machine below also has a palm operated tabulator, seen on the right side of the front frame.
In official Burroughs internal reference, the typewriters were referred to as machines of "Series T."  The machines which were fully manual were Type 50, and those with electric carriage return were Type 60.

In the serial number prefixes, the first number (two digits) is the Type number and increases by one for each increase in carriage width above the standard carriage; thus, both machines here are "one size up" in carriage width.
At left and above, patent illustrations for the Burroughs.  On the left, illustration showing the internal frame construction (lower) and the machine with the exterior facade panels applied (upper.)  Technical view above shows nature of key-lever / type-bar mechanism, which is roughly like that of the Underwood but much closer to that of a number of earlier abortive and unrelated designs.  See December 2006 ETCetera for full details.
Here is an illustration from Peter Weil; it comes from a 1935 trade catalog issued by a company in Brussels, Belgium who was distributing the Burroughs machines there.  It describes the Burroughs Standard Typewriter as "Robust, rapid, silent and fast."  It also notes that the machine was completely new, but that Burroughs had sold over one million other (different) office machines (adding machines, cash registers) and that the same network that supported all of those prior machines stood ready to support the new typewriters.
