I'm a bit baffled by your question?
I have only war diaries, some photos and a few assumptions. I could be wrong.

As I said before yard periods during early 1942 were short for ALL Atlantic destroyers because of convoy/escort requirements. Commonly these short periods were spelled out as "primarily" for voyage repairs. Repairing those necessary items for the next mission (examples, broken radio, radar, sonar, etc) were the priority. "Extras" to add things like armament upgrades and radars, were done during these periods if enough time existed. 28 July to 5 August 1942 would've been adequate for any additions. But, based on the June 1942 report on modifications made at BosNY and the 5 August photos, nothing additional were added during the July-August 1942 period. The photos taken on 5 August 1942, may have been done to make-up for NOT having taken photos after the June 1942 modifications.
During USS BUCK's June 1942 yard period, she got the "ultimate" four 20-mm guns for her class (two on the aft deckhouse and two forward of the bridge). They were arranged differently than the final configuration when two twin 40-mm mounts were installed, when three 20-mm guns were installed forward of the bridge and one aft. You can see that the aft deckhouse was pretty well cleared for "when" the twin 40-mm mounts would be installed and an elevated platform added for a single 20-mm gun. The Pacific Fleet SIMS class units got more 20-mm guns prior to addition of 40-mm guns with four 20-mm guns added on the aft deckhouse, plus two forward of the bridge, making six total. The Atlantic Fleet destroyers prior to the North Africa campaign, were not as concerned about AA armament, because they seldom encountered attack from the air while on convoy duty. After the fleet was engaged in the Med and was being attacked by German air power, the concern changed.
Thank you.
I saw your post about the Norfolk Navy Yard group (DD-409, 410, 414, 415, 416), their photo in December 1941;
Charleston Navy Yard group (DD-411, 412, 413, 417), their photo in January 1942 (but I don’t understand why DD-413 Mastin was different on 14 June 1942);
photo of DD-418 Roe on 6 June 1942 and DD-419 Wainwright on 30 June 1942 (both very similar to Charleston Navy Yard group, but there are some differences - 6 K-gun and ladder from the aft superstructure to the aft torpedo tube platform)
However, I haven't seen the photo of DD-420 on 5 August 1942 and I don’t know what it looked like...
