HO Scale United PFM 3 Truck Class B Shay

Brand new in the box HO Scale United PFM 3 Truck Class B Shay.

The phrase "3-Truck Class B Shay" almost exclusively refers to vintage HO scale brass models imported by companies like Pacific Fast Mail (PFM) and built by United/Atlas in Japan. In the mid-20th-century model railroading community, these models were frequently mislabeled or marketed under this name.
