The impressed stamp T.B. has been recorded many times on a variety of Windsor chair models and not just this particular type of elegant Gothic style chair; see Dr. B. Cotton The English Regional Chair, Woodbridge, 1990, pp.56-58, figs.TV47-57 (fig.TV55 shows the stamp in question). The fact that many other very similar chairs are recorded with a variety of different initials leads Dr. Cotton to suggest that the chairs were probably made at the same time in one workshop using the same manufacturing devices. They were then stamped to identify each individual maker's work. Some of these maker's names have been identified and by cross referring to recorded makers working during the same period Dr. Cotton believes the initials could well be those of Thomas Barrett of High Wycombe (fl.1834-41).
