Pan,
First off, the "boxy" device with six portals are called "reproducers", a fancy name for loudspeaker. They were installed to be "louder" than the previous standard horn speaker. This came in useful for underway replenishment and for communicating with small craft during amphibious operations.
The issue of the early "BENSON and GLEAVES" class units (DD-421 through DD-444) being authorized eight K-Guns is debatable. EIGHT K-Guns were authorized in August 1941, and then reduced to SIX K-Guns in December 1941. None of the Repeat BENSON-GLEAVES class units were completed with eight K-Guns. I'm unsure of Friedman's comment that "a few BENSON's had eight K-Guns" installed in January 1942. I have come across no photos showing eight K-Guns in late 1941 or early 1942. Actually, I have several photos of the early BENSON-GLEAVES class units in January-May 1942 with a Y-Gun still on the fantail and NO K-Guns. However, there is a general gap in photograph coverage of these units during this period and a couple could have been modified. I have an image of one unit with only FOUR K-Guns in the Atlantic in May 1942. A "draft-Red-lined" April 1942 Armament Summary I came across at NARA, shows that DD-423, 430, 437, and 442 still had a Y-Gun. The same Summary has DD-421, 430, 433, 436, 443, and 444 had only four K-Guns. Also, this Summary has DD-426, 427, 428, 434, 435, 438, 439, and 441 had six K-Guns. Armament Summaries most times were NOT up to date since armaments were changing rapidly during the war and was reliant or data REPORTED to the beancounters producing the Summary. I suspect most (or all?) of these units had yet to get ANY K-Guns installed by January 1942. Only DD-427 and 438 had "printed" entries of Six K-Guns in the April 1942 Armament Summaries showing that they were installed prior to an earlier Armament Summary update. Several units do not have any K-Guns of a Y-Gun listed. Also, Pacific class units of the Original and Repeat BENSON-GLEAVES class units were directed to reduce K-Guns to FOUR in the Pacific as a weight saving for additional AA armament, but this doesn't appear to have been followed and apparently was rescinded at some point.
I don't see where your comment about USS BUCHANAN having her quad 1.1-in mount removed and several 20-mm guns added in late 1943 (I assume this was prior to her upgrade to two twin 40-mm mounts) appears in DestroyerHistory.org, please provide where this is located. Removing her quad 1.1-in mount would be very unlikely, until being replaced with twin 40-mm mounts, unless completely destroyed. A centerline platform forward of the bridge would have required a yard period and there is no evidence that occurred before mid-1944. However, there is evidence that the bridge wing 20-mm guns were added prior to her 1944 overhaul. I have an image of USS LANSDOWNE (DD-486) dated 17 March 1943, showing the bridge wing 20-mm guns and a fuzzy image of USS BUCHANAN in July 1943, looking like she also have these wing 20-mm guns. But, both photos show no centerline platform installed forward of the bridge. LANSDOWNE only a month after this photo was photographed at MINY getting the two twin 40-mm mounts and a centerline platform forward of the bridge.
