Passenger Car truck prototypes and assignments

I am hoping that someone can help me find a good resources for matching Passenger car trucks to passenger cars.

I know most lightweight cars have either Type 41 or Type 43 trucks, but is there a good source that has either a table of what the designations are like 41-N-11, or 41-TGV-11 or 43-C-11 etc.  I am going through my pullman library books and trying to identify what types of trucks each car had from the photos. The authors didn't start adding truck type in the photo captions until Volume 7, so its pure guesswork for some of the earlier volumes. If anyone knows a good definitive source, that would be very much appreciated. 

Any help with ATSF, GN, NP, SP&S, NYC, PRR, and SP cars rode on what trucks would be helpful too.

Here is what I have so far, with photos:

Are you planning on printing all of those designs?

Not all at once, I want to identify the correct prototype trucks for the passenger cars that we currently offer, as well as the ones in development, but eventually, we probably will. This list has grown even longer on my spreadsheet. I also ordered a volume of the Railroad Prototype Cyclopedia that has extensive information on Passenger Car Trucks. 

I did find this, but it doesn't seem to match all the variants:

PULLMAN PREWAR CODE:

A - Any truck used at an articulation
U - Truck used under specific Union Pacific-assigned cars
41 - Four wheels, one bolster
43 - Four wheels, triple bolster (SP, UP, PRR, etc)
62 - Six wheels, double bolster
63 - Six wheels, triple bolster
E - Elliptical (leaf-style) bolster spring
H - Helical ("coil"-style) bolster spring
R - Equipped with roller bearings
X - Experimental
11 - 6"x11" journals (5.5"x10" were standard)

PULLMAN POSTWAR CODE:

No designating letter indicates standard 8-foot six-inch wheelbase
A = 7'0"
B = 8'0"
C = 9'0"

No designating letter indicates clasp brakes
D = disk (rotor) brakes

No designating letter indicates 15-1/16" pedestal liner openings (jaws)
N = 13-3/8"
M = 13-7/8" (Milwaukee Road)
U = 14-1/16" (Union Pacific)

No designating letter indicates helical ("coil") bolster springs
E indicates elliptical
P indicates combination of helical and elliptical (Pennsylvania, as on new Walthers "Broadway Limited" cars)

No designating letter indicates no roll stabilization
S = roll stabilizer

No designating number indicates 5.5"x10" bearings
11 (as suffix) indicates 6"x11" bearings

No designation indicates inside swing hangers
O = Outside swing hanger
