InterMountain has scheduled for arrival in Dec. '09 or Jan. '10 four different road numbers for Seaboards' F-3A's. Apparently these will be the phase IIa type (high fan shrouds) and chicken wire (#4022 - #4029). If you missed out on the Genesis units (#4029, 4030, and 4032) of a few years ago you'll probably want to start saving your nickels, dimes, and quarters.
