Stuart: Thanks for your interest.
All are destroyers, foreground: USSR "Novik" class 1915, as in 1942 - Northern Fleet.
Middle Norwegian DD, from Royal Navy, one of the fifty USN 4 stackers (1918) - "St. Albans" which mistakenly sank a Polish sub which was out of its position - the Polish sub was a former USN "S Boat."
The final one is a RN V&W - 1917 - penant D75 "Venomous" - sorry its in the 1940 arrangement and paint job. In 42 she lost A and Y main battery, and one set of TTs, received DC racks and throwers, increased AA and radar, as well as Northern Approaches livery.
The second pix are front - Benham class, rear - Bagley class. I decided the best way to sort through all of the USN classes was to model them all.
