DS/SS split 1945 ATSF help needed

Hi Folks

Here are the DS/SS/Steel splits, 1945 and 1950, for box and auto cars
in interchange service on the ATSF.

January 1945:
ATSF_____%____Number
DS_____17.1%____6,022
SS_____21.7%____7,649
Steel_____45.9%____16,209
Other_____14.4%____5,089
Known_____99.1%____34,969
Unknown_____0.9%____308
Total_____100.0%____35,277

July 1950:
ATSF_____%____Number
DS_____1.2%____432
SS_____21.7%____7,549
Steel_____69.0%____24,024
Other_____7.9%____2,754
Known_____99.8%____34,759
Unknown_____0.2%____68
Total_____100.0%____34,827

These tables exclude DS cars in the series 40000-40024, class Bx-25,
which the ORER describes as "Brick", on the assumption that they are
not in interchange service.

The ATSF retired over 90% of its double sheathed cars, and an even
100 of its single sheathed. It nearly halved its "panel" fleet, but
increased its steel cars by almost 50%. Overall, it had a minor
decline.

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
ATSF, XAP, Auto, 6350-6378, 40'6", 12'4", 12'6", 80000, 26, NA
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
ATSF, XAP, Auto, 8101-8160, 50'6", 10'5", 14'6", 80000, 55, 2
ATSF, XA, Auto, 8161-8259, 50'6", 10'5", 14'6", 80000, 98, 11
ATSF, XA, Auto, 9422-9887, 40'6", 10'0", 10'1", 80000, 26, 9
ATSF, XA, Auto, 62846-62946, 40'6", 10'0", 12'6", 80000, 11, NA
ATSF, XM, Box, 261551-262571, 40'6", 10'0", 6'0", 80000, 17, 4

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

If anyone could inform me about the sheathing type
(DS/SS/Steel/rebuild/panel) and build or rebuild date for above
series, I would greatly appreciate it.
