Hi John,
Your Google is smarter than mine or more likely your query was smarter than mine! I came up empty.
Just a note, the drawing you came up with is the as built version for locos 19-27 which were Vauclain four cylinder simple locos. These were rebuilt in later years as standard two cylinder engines so the rest of the dimensions would still be correct for all of the 2-8-0's. 28 - 58 were built as two cylinder superheated piston valve engines.
The Loco Base info would seem to indicate that engines 19- 27 were lighter than 28 - 41 but were otherwise identical. 42 - 51 were a bit heavier but otherwise appear to be identical to the previous versions.
