The RUDDERROW class (99 ships) are really not similar to the above classes of DE's. In this class they went from the 3x3" open guns to 2x5" 38.cal. turreted guns - one fore, one aft. That's why I left them out. This was the last class of wartime built DE's. Very sleek and handsome ships. Many were converted to fast transports.
Your "FMR" was the CANNON Class. This was a sub-class of the BUCKLEY's. Many of these ships were transfered on the Lend Lease program. USS Cannon DE-99 was transfered to Brazil in 1944.
BTW, research has come up with USS ENGSTROM DE-50 was the last ship in the EVERTS Class. (DE 5 - 50). The BUCKLEY Class started with DE-51
Hey Pongo, a good site for reasearch is

As for the names in CONWAY's - that has "got to be" a RN classification system. I have NEVER heard them called that before, Only by classes. Interesting though, I will have to write them down.
