Further info:

Found a shot in an old Don Ball book of a Southern Railway set with boilers that could be either F-2 or F-3, and Dave has a manual indicating at least that Southern 6700-6701 (F-2A) had boilers, and 800 gallon water capacity.

Gulf, Mobile & Ohio had nine F-3A and three F-3B units with steam generators.

Chicago, Rock Island & Pacific F-2A units 38-49 had steam generators, 70 MPH gear ratio and 600 gallon boiler water capacity.

Erie had seven A-B-A sets of F-3 units (800 A,B,C thru 806 A,B,C) with boilers and dynamic brakes. A units had 800 gallon water capacity and B units had 2000 gallon water capacity. Geared for 89 MPH.

CB&Q had three A-B-A sets of F-3 units (9960 A,B,C thru 9962 A,B,C) with boilers; A units had 600 gallon water capacity and B units had 1800 gallon water capacity. Geared for 102 MPH.

These are not all-inclusive for each railroad necessarily; this info is from railroad-specific operator manuals in Dave's collection with the exception of the GM&O info which is from a book.
