Based on the information here: http://www.tangibilities.com/Bed.html
and additional pictures listed here:
http://www.tangibilities.com/Bedpics.html, who made this bed? 
Catalogues of furniture makers c. 1815- 1835 would be a souce.  We
will accept a locality of its manufacture if a manufactuer cannot be
determined.  Please include images or methodology of how you
determined the maker.  Construction techniques and design of this
bedstead (see images) show probable manufacture in Philadelphia, New
York, Boston, or a southern local...but we are not positive. Thank
you.
