I've been trying (with a lot of help on Matt Conrad's parktrains.com) to track the whereabouts of all of the 36" gage 25 ton Crown 4-4-0's (there were at least 18 of them built from about 1962? to 1975). Six Gun #7 is in Jefferson, TX as stated on this site. As best I can tell, the one static displayed on the plaza between Underground Atlanta and the Coke building is Six Gun #4. It is robbed of parts and has Warner Brothers cartoon characters in the cab. Both engines appear to have lubricators cantilevered over the front of the left cylinder which the Six Gun engines in Ocala/Silver Spring, FL had.
If you ever have a fix on where that Glover is in Ohio, I'd love to know. I'm in Cincinnati.
