I just had the chance to read this thread, and wanted to pass on a couple of observations. First, those "triangle repairs" to the drop down front look as if someone attempted to try to break into the locked desk with the use of a tool / knife causing some good sized chips that needed to be patched. Second, the piece appears to have been around long enough to have wore the drawer sides down to the point where they were built back up with replacement wood.
That being said, my thoughts would be that the piece is around a hundred years old. Regardless of age, with the restoration that it shows, the market value is going to be held down.
