i have an antique roll top desk that i am trying to find more about. it is in good shape. the only thing that doesn't work is the lock mechanism. I could replace it, but I do not want to decrease any value, if there is any, in the desk. the lock plate reads "WM Richardson, Leeds & Bradford, office furnisher." the desk is pretty on all four sides. it appears to be oak. can anyone tell me anything about this desk? I can send pics. I ultimately want to know if it is worth much.

thank you for your help.
