Class P #306 - Phantom engine or not?

[Luke]

To commence operations over the newly assigned Northern Ohio Railway in 1920, AC&Y acquired twelve (12) surplus 4-6-0 Class P locomotives from the NKP. Most were rebuilt/modernized by American Ship Building at Elyria. There is, however, an unexplained anomaly... phantom engine No. 306 does not exist in any AC&Y records.... yet here it is, photographically preserved on the Brittain turntable. The air tank stencil reads “Tested September 4, 1920 - ASB”. Another riddle for the ages?

As Confucious (supposedley) said: "One good picture-----------". I have a copy of the little booklet: Motive Power Equipment (blueprinted, hand lettered pages between linen covers) that dates to just after the acquisition of the 401 (1930?). It lists 12 of the Class P engines but, as you said, no 306.
