Roger, as Cal mentioned, I made a few of these lowboys a few years ago (I am flattered he remembered). I scaled mine from pictures of a Goddard piece that sits in the state department rooms. I can get you some measurements if that would help. And as Freddy recommended, if you are looking for accurate measurements from an original, get in touch will Al Breed. I got plans for a Townsend highboy from Al, from a piece he had measured himself. This was after I had built the lowboys and had been a little frustrated at the lack of detail I was able to get from scaling pictures, such as moldings, joinery, etc. I wanted to build a highboy that would be an Exact copy (as far as I could) of the original. The best thing would be to gain access to an original to measure yourself. This is a great way to learn about antiques. I have measured two originals at the Conn. Historical Society, and would highly recommend contacting some local museums.
