A pair of mast wheels, replicas of those used to haul enormous tree trunks for use as masts in the 18th century, were delivered to a Portland boatyard Thursday.

Twelve feet in diameter and weighing 1,000 pounds each, the wheels were built three decades ago for Story Land amusement park in New Hampshire, but they had to be moved to make way for a new exhibit.

The wheels have found a new home at the Tate House Museum in Stroudwater Village. Officials there said they hope to put the wheels on display near the museum.
