Longer B3-style format
The B6 is described as a longer version of the B3.

Independent shopping perspective
The gold B6 is the longer B3-style Bigsby tailpiece for larger-bodied archtop guitars. Its length is intended to maintain the proper string angle on instruments in that format, while the wire handle provides the control point for gentle vibrato movement or more dramatic pitch sweeps. The description specifically identifies the Gretsch 6120 as an example of the larger archtop guitars this B6 is designed around.
