There is a difference in the specs for the fire box. This probably accounts for the difference in length.

If this was done in ink it was not a fast drawing. In pencil it was a bit easier, in autocad fairly quicker and if the second drawing person had access to the first drawing the length could be changed in about 30 seconds including thinking about it.

Using ink or pencil and not concerned with scale if you had access to the first drawing you would make a sepia (a copy on a blue print on special semi transparent paper) and make the changes on the sepia.

Having used ink, pencil and autocad I much prefer a cad system.

The difference is in the firebox as mentioned. Note that one firebox is WAT 1926 and the other AlCO 1925. The note on the AlCO also states a third course. This would refer to the brick lining inside the firebox where the coal and fire were made. The extra two inches is probably the extra course of bricks as firebox lining brick were roughly 2 inches in depth. There is an ALCO technical and Historical Society that may have the detailed specs.
