Mike,
You are correct about 123. It is one of the Henchel 2-8-2's and is on display in Cusco on the road to the Airport. I am sure the PeruRail people would like it back for charter work. The 102 is not one of the SV locos. It was at the Cusco and Santa Ana and survived long enough to be sent to Lima for the display at the City Park in Miraflores.
I visited the Sumpter Valley back in 1999 during the National Narrow Gauge Convention in Portland. I had a great visit and rode the line. The SV group has a great operation. Considering how isolated from the major population centers of the Northwest it is a great accomplishment to have completed the amount of restoration that has been done.
I also was curious about the status of the remains of the ex-Uintah/ Sumpter Valley Mallets. I have seen pictures taken in the 1970s of the one loco without a tender and the boiler empty of flues. The other seemed to be partially intact. In the 1970's the Army of Guatemala scrapped several narrow gauge engines to buy ammunition for the army. Is this story true? Does any parts remain of the mallets?
Hope to get organized soon and add more to the website. I moved in June 2002 and we have been out of the country for a few months. I have a new Sn3 basement with nice house on top. The backyard is big enough for Fn3/GnM. The old Cincinnati, Lebanon and Northern narrow gauge line to Montgomery, OH. ran almost in the backyard.
