As one of the technical/historical references to Bachmann I can tell you as most of you have figured out the two undec versions are very generic.
The one you have is close to 340 today and 340 before the straight side tender she got from 345. As is today 340 has 11" pumps like the model. If you built it as an earlier version it should have 9" pumps and the old D&RGW logo. 9" pumps can be bought.
Yes it would also need the second air res on the engineers side, this can also be bought/made.
Or if you can live without it a very nice loco can be built.
340 build
Fallow the link to two builds out of B-mann c-19s.
Track side details makes most of what you would need to modify them as you please. You can also find parts from Precision scale, Ozark minitures, and Hartford products.
Also there was only one c-19 with a steel cab during the days of the Grande. That was 346 after her roll over. Today 340 and 41 have steel cabs built to look like the wood cabs, but will last longer. Your loco is a wood cab but has the steel sheathing.
