Circa 1905-07. The first series No. 1 locomotive was actually the same as the 3rd Series No. 0. The only small locomotive cataloged from 1901-1904 were the No. 0 and the No. 3. These small tin clockworks always came with early FE No. 1 tenders. Below is a No. 1 in black with it's tender.

This blue boiler No. 1 has an unusual butterscotch roof.
