Just letting you know I got this one.
Could you do me one favor and add another photo of the dovetailing in one of the lower drawers. It helps a great deal with dating a piece like this.
Good morning Carlos,
This style of writing desk is French and known as a secrétaire à abattant ('abattant' meaning drop-front) which first became popular in the late 1700s. Yours is a little later, judging by the shape of the cornice molding and other features such as the barley-twist columns in the arcading in the fitted interior, it dates to the "Louis Philippe" or "Charles X" period, circa 1830s.
Judging by the wood of the exterior that looks like it might be cherry, it may be American made.
At a well attended auction this piece would sell in the range of $1200 - $1800.
It therefore has a full retail/replacement/insurance value of $3600.
Hope this helps!
