Readingfan: I don't want to start a fight but my understanding is that the group had at least two T1's. There are four still around 2100 being restored in OH, 2101 [Freedom train Engine] at the B&O museum in Baltimore, 2102 owned by Reading Blue Mountain and Northern, Port Clinton, Pa. being restored (Google their website), and 2124 on display at Steamtown, Scranton, Pa.
Don't know if Kughn was a member of the Ross Rowland crew that restored 2101 for the freedom train as mentioned above. Ross I believe was an adviser to the group that restored 2100 and 2102(?).
By the way, just read your bio, I also live in a Sears prefab.
