Question. I have a few post war 0-6-0’s with the slope back tenders. I have two 21004s, one 21005, and 4 shells that are numbered 21004, and lastly one custom repaint in NKP decals. The first question is when did the 21004’s come out? Second, the 1957 catalogue shows a 0-6-0 numbered in a 3 digit series ( cannot rememeber the no. was 347 maybe?) But I cannot find any ever made? Next question is when was the 21005 made? With the extra shells I have, I would like to return the custom painted 0-6-0 to original, how do I determine what year the custom painted 0-6-0 was made?
Thanks for the help and Run Those Trains!
