This pen is a variation of the Cambridge. It has a solid metallic (gold or silver) center band instead of the black band found on the Cambridge. Although it is a variation, the tube dimensions and fitting sizes are different than the Cambridge. The Cambridge bushings will not fit the Roman Harvest.
