RJ HORNER SECRETARY DESK??

This desk belonged to my grandmother. My aunt is going to give it to me soon. I have no idea how old it is. It is in great shape. My grandmother used it to write letters to my grandfather back when he was in the war. She had used it in more recent years to store old paperwork .  The closest thing i could find to this desk on the internet was an RJ Horner desk made in the 1800s.  I dont have the desk yet and im not sure if it has a name on it anywhere. Im looking to find out if anyone could tell me the name and value of this desk ??
