HUGHES TOOL <HT> UP ON MERGER SPECULATION Hughes Tool Co rose one to 12-1/4 on 1,658,000 shares, apparently reflecting a belief that Baker International Corp <BKO> will be able to persaude Hughes to go along with a previously announced merger, analysts said. This week Hughes seemed to back out of the merger but then said it was still interested in talking. "It sounds like Baker wants it and if people are convinced a deal is going to go through the stock goes up," said analyst Phil Pace of Kidder, Peabody and Co. Holders of Hughes would get 0.8 share of Baker for each Hughes share.
