This left-side view of Mohawk No. 3137 was snapped at Elkhart, Indiana in the 1940s; notice that the cylinder cap, missing on my 1955 photo of No. 3137, is still in place and the air pump shields above the pilot have not been modified. This image came to our collection via Wayne Koch and also appears in the Railfan.net ABPR Archive, uploaded by Bud Laws but without attribution to the original photographer.
