Bruce,
There sure was a lot of confusion, which still persists today. According to the pictures on your webpage, 10 & 14 were shipped from the ET&WNC in May 1942. Preston's picture shows one of them [supposedly 14] during the winter of '42 on the steel bridge. The fluted stack cap is in place and the smokebox is uninsulated. Other pictures on your webpage show them being unloaded at Tacoma WA, and the date is stated as 12 July 1943. The fluted stack cap and uninsulated smokebox is evident. This date is further supported by a Trains magazine article attributed to September 1943 although the date does not show on the magazine image. Further images show 10 on the WP&YR after the overhual which removed the stack cap and insulated the smokebox. In these images the engine is fitted with a plow, the photo location is Skagway, and is probably Fall 1943 before they went to Whitehorse.
The point which prompted my question is that after returning from Tacoma 10 still has the tender lettered W.P.& Y. R.
If they were Army engines I wonder why the tender isn't labeled USA like the other Army engines?
The confusion is augmented by the quote in the post above from Johnny Graybeal's "Along the ET&WNC" vol 2: which clearly implies they were sent from ET&WNC directly to Tacoma, overhauled, and then sent to Alaska. Of course that's quite unlikely as evidenced by Preston's photo.
Do you have more of the September Trains magazine which confirms that it's 1943, since that's the evidence which supports the 1943 date on the Tacoma photos?
