Antique Roll Top DESK - $600 (Ventura)

Antique roll top desk, I do not have a key for it.
It is about 42 inches wide x 30 inches out from the wall.
My guess is that it dates before 1900.
It is old so there are stains, scratches, dings, and 2 stress cracks in the top.
The drawers and the roll top all work fine.
I believe the wood is oak.
