This Ink well was used I think that the man use it would shake his pen off on the ink well. I have cleaned as much as I dared but was afraid that I would lose the Patina. So I leave the rest to you. The ink well is 8 1/2 Inches wide and 6 inches in a stair step from the pen holder to the bottom. There are two ink holder with brass caps and two white ink holder with lot of blue ink stains on them.. For you from the High Plains of Kansas!!
