There are 2 photos of USS St. Louis berthed at the Pearl Harbor Navy Yard in 1941 wearing MS-1/5 camouflage. These photos show her at berth B-21. She arrived at this berth on 10/2/41 and left that berth on 10/9/41.
These 2 photos also show USS Breese DM-18 and USS Montogomery DM-17 berthed at B-18.
Both Breeze and Montogomery are wearing MS-1 camouflage.
But if you take a closer look at the port side hull of USS Breese (the ship on the right), you can see a bunch of scaffolding hanging on the hull.
This next photo was taken on 10/10/41. In this photo, USS Indianapolis had just docked at berth B-21 and USS Raleigh is building up steam to leave berth B-17. Indianapolis is wearing MS-1/5 camouflage and USS Raleigh is wearing MS-1 camouflage. Just ahead of USS Raleigh, we can see USS Breeze and USS Montgomery at berth B-18.
If we zoom in and take a closer look at Breeze and Montgomery, their hulls are no longer painted MS-1 (5-D).
Just a small portion of USS Breeze's bow appears to be still 5-D. The rest of it has clearly been painted a different color.
In my opinion, we are looking at USS Breeze and USS Montgomery transitioning from MS-1 camouflage to MS-11 (overall 5-S) camouflage.
If that is the case, then this is the first two examples of 5-S paint being applied to a ship at Pearl Harbor.
The next two ships (that I'm aware of at this point) to receive a MS-11(5-S) paint job were USS Raleigh and USS Detroit.
