Circa 1911, this variation has a hook coupler, full red trim on steam chest, the wheels are held on by hex nuts.

Circa 1912 - this one has the automatic coupler, black steam chest with lots of red trim. Someone chopped the cast headlight on this one and replaced  it with a homemade electric headlight, but we wanted to show this one with the extra red trim, every once in a while an early steamer shows up like this.

Always cataloged with a No. 11 tender (as below), this number 1 tender is approximately the same era.

Circa 1914-1915 - Note that it has straight drive rods.

Circa 1916 - Rubber stamped variation.
