"The launching of the APC 4 will take place tomorrow [August 29, 1942] at 9 o'clock at the lower yard of the Herreshoff Mfg. Company.
Mrs John Millar, wife of a construction foreman at Herreshoff's, will be the sponsor of the APC 4. Co-sponsors will be her two daughters, Barbara and Jane.
This marks the fourth of the special task naval vessels, known as the APC type, to be launched at Herreshoff's.
The APC 3 was launched Wednesday [August 26, 1942] morning with Miss Margaret L. Hibbert, daughter of George Hibbert, as sponsor." (Source: Anon. "APC 4 To Be Launched At Herreshoff's Tomorrow." Bristol Phoenix, August 28, 1942, p. 1.)

"The launching of the APC-4, special task navy vessel, at the Herreshoff Manufacturing Company yards, Saturday morning [August 29, 1942], was also the occasion for an expression of tribute on the part of Carl W. Haffenreffer, general manager, in honor of 59 long-time employees at the plant.
The APC-4 was the fourth of its class to be sent down the ways at the local shipyard, and it slid into the water with colors flying in true launching style. Sponsor of the new vessel was Mrs. John Millar, wife of one of the plant foremen, and with her were her two daughters, Barbara and Jane, as co-sponsors. The young ladies were presented with the container for the bottle of wine used in christening the ship, as a souvenir of the launching.
Mr Haffenreffer raised the service rendered by the older employees in serving as a nucleus for breaking in the hundreds of new men who have been added to the company's payroll since the period of naval construction began. He also revealed that contracts for more vessels have been secured which will keep Herreshoff's busy at least until the middle of next year.
The 'old-timers' mentioned by Mr Haffenreffer were: Fred F Hodedon, Charles W Wall, Ralph Bradbury,
Willard S. Kenney, J. Thomas Ashton, Thomas P Brightman, Christie Lewis, Frederick Moore, Harry Starkey, Harvey Dunn, Manuel King, Charles Peterson, Charles Davis, A. Sidney DeW Herreshoff, Walter Handy,
M. L. Mott, Napoleon Patenaude, William Darling, Rocco Migliori, Harold F Green, Harry Town, George Hibbert, Herbert F Newman, Arthur P Sherman, William Cook, Manuel Cardoza, Herman Gabrielson, Leo E Haves, Otis M. Bailey, Charles Martin, William Simmons, Walter Kilner.

"Twenty-two of these 'jacks of all trades' were built between October 1942 and July 1943 --- with an average of nearly one of these 103-footers each week. Each cost $145,750, and they appear to have been contracted for in two batches, with the lead ship [#425p] of the class (APc 1) included in the first batch of ten; APc 85 [#500p] through APc 96 [#511p] constituted the second batch. It was an impressive rate of production, especially so because the APcs were built concurrently with eight 71-foot British Vosper torpedo boats, which were built in the South Construction Shop."

Note: The transcription of the HMCo Construction Record by Peter Vermilya and Maynard Bray was performed independently (and earlier) than that by Claas van der Linde. A comparison of the two transcriptions can be particularly useful in those many cases where the handwriting in the Construction Record is difficult to decipher.
