Mark,
One of the signature details on this piece is the dart or arrow pattern banding, which is found on the mirror surround, and also on the edges of the mid-top. There is an excellent article showing in detail how to make this banding. This article is entitled "Making an Arrow Banding: A Seymour Detail Explained", and is found in the SAPFM's annual journal:
'American Period Furniture', Journal of the SAPFM, Volume 5, 2005; Philip C. Lowe with Austen Winters, p. 16.
This article also shows a good photo of the mirror surround, so you can see what is happening there.
