Re: trivia? D&RGW ng locomotive photos

I have seen pictures of all of the following NG engines:

T-12s
C-17s (I believe)
C-18s
C-19s (only one of 348 & 349)
C-21s and 25
All of the K class

Most of the C-16s have been photographed but I have no way to guarantee all. There are very few pictures of all the earlier engines, and I don't know all of the various classes or the quantities in each.

I dont know if there is one of each K-27 in either of the Compound or Slide Valve configurations. I have only seen one of the C-18 engines pictured in the 424-429 numbering (424, later 320). Not sure if I have seen a picture of 420 (RGS 42) before being sold to the RGS. Only a handful of pics of the C-19s in the 400 series numbers.

Another interesting question would be, How many of the engines are there builders photos of?
