Rich Melvin posted:kgdjpubs, you just discovered something that I never really noticed, but it is correct.
Here is the original, hand-drawn diagram from the Lima Locomotive Works that I used to make the diagram in the computer. That same offset is there.
I think the offset is there because there are a couple of appliances on the Fireman's side, such as the cold water pump and the feedwater hot water pump that demand slightly more clearance on the left side.
OMG! where do you guys gt this stuff!!! That's why I love this forum!
Kudos to you all!
