We have a few pointer here to help you think through what to look for in a desk and a suppler. For example we would suggest finding a reputable antique dealer rather than risking a purchase from an online auction site who's descriptions may not be accurate. So we would recommend finding an antique furniture dealer who offers customer protection, has a returns policy
if you are not happy and can supply a certificate of authenticity on the age and description of the piece you are buying.
