This is a two piece secretary in maple (?). I have searched through out the internet and am unable to find a photo or listing of a secretary that is anything like this one. It was purchased in the 60's at an estate sale in Sewickely Heights, Pa.
The top portion (photo attached) is is shown without the pieces that create the "panes" but I have all of the pieces. The desk part is different in that it is not a slanted front like a traditional secretary would be; it looks like a drawer but pulls out into a small writing surface with shelves on each side and a little door/compartment in the center.
I have the key to the glass book/plate case (the top part of two pieces). One drawer is missing one handle. More pictures are available.
There are no markings but it is a quality and heavy piece of furniture. I have no idea of what it may be worth, but I would like to sell it for what it is worth.
Re: Secretary Federal?
It's a modern piece, which tend to be a mix of styles such as Federal and Chippendale. Post up a full image of it, some shots of the drawer and door construction and I could tell you more about it.
