Mt.Aetna ran ALFs of various models and vintages from their start around 1970. This one, a 1948 700 series 1500/300, came from the Western Enterprise VFC #4 of Hagerstown,MD.
The ALF behind this is 1 of 2 1973 ALF engines from Silver Spring,MD., but these rigs passed to a Carlisle,PA. collector.
The 700 series is still privately owned, I think.
