The work on these units was held up shortly after the order was placed. We have been trying ever since that time to obtain the exact status of the order from Rolls-Royce, Ltd., but since neither Taft-Peirce nor ourselves have received any information, we believe it should be assumed that the order has been cancelled. | ||
