A lot more than these three 6-Gun (3-in) ASW Flush-Deckers wore this Ms 2 scheme designed for them. There were in total 27 6-Gun units, of which 18 were modified before camo schemes changed in early 1941 (DD-118, 142, 144, 145, 152, 153, 154, 155, 199, 210, 220, 221, 223, 229, 239, 240, 245, and 246). The last 9 units (DD-126, 128, 130, 147, 157, 158, 159, 160, and 341)were modified in September 1941 and were painted in Ms 12.
When units were first painted in this Ms 2 scheme, it appears that they didn't apply the hull number initially.
This Ms 2 scheme was illustrated in the early 1941 Camo Instructions. Shown on a basic "Flush-Decker", it appears to have been ONLY applied to the 6-Gun ASW units.
I have or found about a dozen units from the first 18 painted in the unique Ms 2 scheme, including DD-220, 221, 223, 240, and 245. The unit photographed alongside side USS NORTH CAROLINA in April 1941, is USS SIMPSON (DD-221), NOT USS RUEBEN JAMES. Verified from Deck Logs.

Gents, I’ve searched my saved pictures and queried Rick and Jeff without luck. One of the posters from a few years back (not found in the site archives) posted the best picture of an escort modified 1,200-ton flush decker in a graded system in what we believe was running trials out of the NYNY mid 1941. Level, port bow view of the entire ship. Anyone remember or save it? Inquiring minds want to know.
