There are over 300 cars in 1945 whose sheathing is
currently "Unknown", with most of them in the following series:

Road, AAR, Kind, Series, IL, IH, Door, Capy, Qty 1945, Qty 1950
ATSF, XAP, Auto, 6330-6347, 50'6", 12'4", 14'6", 66000, 15, NA

Class Fe-13, rebuilt as steel sheathed cars in 1937, modified during WW
II with extended roofs for aircraft and auto parts service.

ATSF, XAP, Auto, 6350-6378, 40'6", 12'4", 12'6", 80000, 26, NA

Class Fe-15, rebuilt as steel sheathed cars in 1937, modified during WW
II with extended roofs for aircraft and auto parts service.

ATSF, XAP, Auto, 6450-6460, 50'6", 12'4", 14'6", 71000, 12, NA
ATSF, XAP, Auto, 6550-6569, 50'6", 10'10", 14'6", 76000, 20, NA

Both Class Fe-13, see above.

ATSF, XAP, Auto, 8101-8160, 50'6", 10'5", 14'6", 80000, 55, 2

Class Fe-9, rebuilt as steel sheathed cars in 1936.

ATSF, XA, Auto, 8161-8259, 50'6", 10'5", 14'6", 80000, 98, 11

Class Fe-11, rebuilt as steel sheathed cars in 1936.

ATSF, XA, Auto, 9422-9887, 40'6", 10'0", 10'1", 80000, 26, 9

Class Fe-L, built by AC&F in 1909 as double wood sheathed automobile
box cars and never rebuilt; the few remaining cars in this class were
retired soon after WW II ended.

ATSF, XA, Auto, 62846-62946, 40'6", 10'0", 12'6", 80000, 11, NA

Also class Fe-L, see above, but equipped with 12'6" double doors.

ATSF, XM, Box, 261551-262571, 40'6", 10'0", 6'0", 80000, 17, 4

Class Bx-19 and Bx-20, converted to box cars from wood-sheathed auto
cars of class Fe-N and Fe-O and renumbered by adding "2" to the
original numbers.

I think the following series is DS, based on a Charles Winters photo
of 62723 posted on the NEB&W site. However, Folio 211 on the Santa
Fe Railway Historical and Modeling Society web site lists part of
this series (62000-62049) as class Fe-25, which is steel sheathed
(and 50' !?!):

ATSF, XA, Auto, 61510-62750, 40'6", 10'0", 10'1", 80000, 63, 24

Surviving cars of Classes Fe-N and Fe-O, these were wood sheathed auto
cars built by AC&F in 1914 to essentially the same design as Class
Fe-L. All of these cars had massive steel underframes with four
fishbelly sills; most were rebuilt during the 1930s into steel sheathed
cars of classes Fe-5, Fe-12, Fe-15, and Fe-19. The few that weren't
rebuilt were rapidly retired after WW II, freeing up the number series
for the postwar renumbering of some Class Fe-25 50' steel double door
auto cars; these had been rebuilt as steel sheathed cars in 1942 using
the underframes and ends of Fe-Q class sectional wood sheathed auto
cars originally built in 1924.
