Antique sideboard or dresser.

Can anyone tell me something about this piece that i bought at a yard sale over the weekend.
It has hand made dovetails, with square nails in spots. It also has square pegs that you can see in one of the pictures.
The bottom of the drawers was made with a flat piece of board that was planed on the outside edges to fit in the grove of the side panels.
The top measures 15 1/2" deep and 45 1/2" long and overall height is 39".
All drawers has a lock on it.
I'm not sure what kind of wood it is but it is heavy. It is all solid wood with no veneer.
As you can see in the pictures it has different shape drawers on it.
I am interested in how old it might be and maybe somebody knows where it might of been made. (what Country). Ans also what it really is. I am guessing some kind of sideboard.

Email Address: norbon@sympatico.ca If you need another picture of it.

Thanks all..
