Jim,
Some notes about the Flush-Decker Minelayers, Minesweepers, and destroyers at Pearl Harbor in December 1941. First off, Pearl Harbor had been the home base for the Pacific Minesweepers and Minelayers for many years prior to 1941.
I notice that you are modifying your Minelayer (and maybe Minesweepers?) models with what looks like the configuration after the Pacific Fleet units of these types were upgraded with 3-in guns in place of the 4-in guns (circle gun tubs forward) AFTER the attack in 1942-43. The Flush-Decker APD's received 3-in guns prior to the DM-DMS as far as I can tell. From the limited photos I have, most are overhead views of Pearl Harbor showing all flush-deckers with 4-in gun, these units still had 4-in guns in December 1941. Even the Flush-Decker Mine Warfare units based in the Atlantic still had 4-in guns in December 1941. In the last half of 1941, both the minelayers and minesweepers were getting overhauls/modifications. In the weekly overhaul reports priority was getting sonar, ASW upgrades, prep work for radar, and improving mine sweeping gear. There was no mention of 4-in gun to 3-in gun replacements. Also, you show mid-war 20-mm gun tubs when there weren't any 20-mm guns at Pearl Harbor during the attack. See attached Weekly overall reports for 10 November and 24 November 1941.
Also, USS SCHLEY (DD-103) would look similar to USS WARD, but USS CHEW (DD-106) was unique among the Flush-Deckers in WWII in still having her aft 4-in gun on the main deck and not on the aft deckhouse. She retained her aft 4-in gun on the main deck all the way through the war. See attached image.
