Hi,
With the help of others, we have located the plans for the Class 45 1/2 4-6-0. I did not realize that the T12 was not the only class of 4-6-0s on the D&RG(W).
Many thanks for all the help.
For completeness, I am presenting the complete index once again.
Hi,
I hope some find this useful. I have tried to list all the NG classes and list them and their cross references and known published plans.
Please take this as a starting point. I am sure I have errors.

DM (SV 101/D&RGW 50) - NMRA Bulletin 1972
OK here's the bit. The D&RGW classification system used after 1924 usually gets shortened a bit. The full designation is actually {letter}-{TE}-{wt}[1] for ex: T-12-47
so under this system we have:
C-17-70 (300-304, RGS 42)
C-17-71 (306)
C-18-72 (315-320)
C-19-70 (340-349, RGS 40, 41)
[data from D&RGW Folio #7 (CRRM reprint)]
Now at some point ISTR remarking that after all the rebuilding it would have made more sense for the C-19's to be 74 at the end *but* AFAIK they never were.
Pre 1924 the Classification system just ran on the engine wt, with an S or N appended sometimes to indicate gauge. So under this we had:
Class 70 (400-411, 417-422) [became C-19, C-17]
Class 00 (427-432) [became 317-319, 360,361,375]!?!
[from reprint of 3rd Div tt #100, 3/28/1920]
or
Class 70 (400,401,403-408,410,411, RGS 40,41 417-419,421,422, RGS 42)
Class 72 (424-429) [became 320, 315-319]
Class 93 (430,431) [became 360,361]
Class 112 (432) [became 375]
and
Class 71 (554,555) [became 305,306]
