I went to the Lomita Railroad Museum probably 10-15 years ago and at the time did not know what the RGS was. It makes you wonder what the backstory is on how this headlight from RGS #22 ended up in Southern California. I have heard that parts from #22 & #25 ended up on some of the other RGS engines. I do not know for sure but it is possible that some of the other parts are over at Knott's (maybe Jeff or one of the other veterans could answer that). I am going to try to head over there tomorrow and check this out. Very interesting find.
