This Amendment No. 3 to Schedule 14D-1 further amends and supplements the Tender Offer Statement on Schedule 14D-1 (the "Schedule 14D-1") originally filed on May 21, 1999 by WGC Acquisition Corp., a Massachusetts corporation (the "Purchaser"), and Precision Castparts Corp., an Oregon corporation and the sole shareholder of the Purchaser ("PCC"), relating to the offer by the Purchaser to purchase all outstanding shares of common stock, $1.00 par value per share (collectively, the "Shares"), of Wyman­Gordon Company, a Massachusetts corporation (the "Company"), at a purchase price of $20.00 per Share, net to the seller in cash, upon the terms and subject to the conditions set forth in the Offer to Purchase dated May 21, 1999 (the "Offer to Purchase") and in the related Letter of Transmittal (which together constitute the "Offer").

Capitalized terms used and not otherwise defined herein shall have the meanings given such terms in the Schedule 14D-1.

Item 10.     Additional Information.

The information set forth in Item 10(b), (c) and (f) is hereby amended by adding thereto the following:

On July 30, 1999, PCC and the Company announced that, on such date, each of them submitted to the FTC the documents and information requested by the FTC in its request for additional information under the HSR Act. PCC has agreed that it will not consummate the proposed acquisition until 20 calendar days after both PCC and the Company have certified compliance with the FTC's request for additional information unless the FTC agrees to an earlier closing date. As a result, the expiration date of the Offer (which is currently scheduled to expire at midnight, New York City time, on Tuesday, August 17, 1999) may need to be further extended, depending on the status of the FTC's review of the documents submitted. The press release of PCC and the Company, dated July 30, 1999, announcing the submission of the requested documents and information to the FTC is incorporated herein by reference to Exhibit (a)(11) to the Schedule 14D-1.

Item 11.     Material to be Filed as Exhibits.

(a)(11)     Press Release dated July 30, 1999.

Signature

After due inquiry and to the best of my knowledge and belief, I certify that the information set forth in this Statement is true, complete and correct.

Date: August 2, 1999
