Maybe the Also Historical Society (or whatever their formal name is) would be able to help?

Darn auto-spell-coreect ALWAYS changes "Alco" to Also.

Just a "heads-up": The yellow high hood in the first photo has replacement windows with rubber grommets and rounded corners, as used by Alco starting in 1950. Original high hood windows have wood frames and sharp corners.

I ran a few HH1000's in the yard at Los Angeles. They were kind of endearing oddball engines. I think ATSF had 15 or more of them. To an Engineer, the big difference was the electrically-driven air compressor, and its somewhat more modest output, when compared to the S2 and S4 switchers (which had air compressors driven directly by the diesel engine). For that reason, Santa Fe did not switch passenger cars with high hood Alco-GE's, unless absolutely necessary. Passenger cars require a larger volume of air to operate the water system as well as the 110 PSI brake system*, and - unlike freight cars - may not be switched without air brakes in use.

* In the classic era brake pipe pressures were lower on most railroads, east of the Rocky Mountains -- 80 PSI for freight and 100 PSI for passenger, vs. 90 and 110 PSI, respectively, in the west.
