If you're looking at this you know all about the relationship between Alco and GE relative to the production of the gas turbine locomotives delivered to the Union Pacific Railroad. This is the first specification developed for these locomotives with a huge 55+ inch fold-out outline or general arrangement drawing. This specification follows the typical subsections found in both GE and EMD specifications covering cab, air brake, etc.
This is an original and is not a copy and is part of my extensive railroad memorabilia collection.
