Description:
Vintage matched pair of framed E-M Diesel Motive Power technical display diagrams.
Both framed pieces appear to show the same Electro-Motive / E-M Diesel Motive Power cutaway engine illustrations for the Model 12-201A engine, Plate 2702, along with Cylinder Head Pot Type, Plate 2751. The diagrams are color-coded to identify air, fuel oil, lube oil, water, and exhaust flow paths.
These are a great pair for collectors of:
Railroadiana
Diesel locomotive memorabilia
Industrial technical displays
Engineering office decor
Machine shop / garage wall decor
Vintage transportation collectibles
The 201A engine was one of the early diesel engines used in Electro-Motive/EMC locomotive development in the 1930s before later EMD powerplants took over, which makes these diagrams especially appealing as early diesel-era railroad display pieces. Electro-Motive became Electro-Motive Corporation in 1930, and the company was reorganized into GM’s Electro-Motive Division in 1941. The Winton/EMC 201A was used in early EMC railcars and locomotives in the 1930s. 
Both charts are the same image/design, just in separate vintage frames. They display well and have a strong mid-century industrial / railroad office look.
Condition:
Vintage pre-owned condition.
Both framed pieces show age and display wear consistent with vintage industrial wall charts. There is visible toning, light spotting, dirt, and general age-related wear to the printed surfaces. Frames show finish wear, scuffs, and edge wear. Backings show age and handling wear. I did not remove the charts from the frames for further inspection, so they are being sold as found/as displayed.
Please review all photos carefully for exact condition.
