So I believe this to be:
GN GREAT NORTHERN 4-8-2 P-2 #2519, Not in original box. I believe it is the correct tender, but wrong box.
Message me if I'm missing something or if incorrect, or if you know more about this than I do with google.

 




Disclaimer - I inherited this collection.  I know absolutely nothing about this hobby.  You can ask technical questions, must likely I will not know the answer.  I still don't know the difference between DCC, DCC equipped, sounds, etc.  With that said, my listings may contain errors.  If you see an error let me know.  I use eBay to help with descriptions, and sometimes the auto populate is wrong. Thanks.
