David,of course regional differences are well known. I want you to be aware that some of the pieces of furniture,such as attributed to Scott,or whoever else,is based entirely upon Wallace Gussler's opinion. I'm not saying he's wrong,but there is no labeling on hese pieces,so everything is based upon features,such as the flattened ball and claw foot,that Gussler attributes to various makers. Some of the provenance of pieces are based upon family traditions. If you watch the Antiques Roadshow,you will many times have seen family traditions be way off of dates,and areas where the owners thought a piece came from,sometimes by hundreds of years,and thousands of miles.
We have only ONE signed piece from 18th.C. Williamsburg: a masonic chair signed by Benjamin Bucktrout,stamped into the back,and misspelled.
