Information on an E.H. Stafford (Chicago) Roll Top Desk

This roll top desk has been in our family for as long as I can remember, myself 
being 36.  The name plate on the desk reads "E.H. Stafford Bros. Chicago".  It 
measures 54"W X 33"D X 52"H and is in superb condition, complete with 21 
cubby's, writing tablet drawer, 7 deep pedestal drawers and a typewriter 
cabinet.

Now, I'm no antique expert by any means.  With that being said, I have never 
seen another roll top desk with this typewriter drawer before.  A shelf that 
you pull outward and upward (then lifting the housed typwriter to a typing 
position) is concealed by a door that matches the rolling top.  The desk is 
completely paneled, including the back.

Any thoughts on where I might go to determine its value and/or history?  A 
google search leads me nowhere.  I have pictures of the desk in question, if 
that would be helpful.  Just e-mail me.

Thank you in advance!

All the best,

Drew
