Great Northern - need builders plate images of R2

[Anonymous]

Greetings,
I need to get builder's plate photos, images, and/or drawings for the R2 steam and W1 electric engines. Any help and/or leads would be greatly appreciated. Also any photos showing the exhaust and the exhaust ports for the W1 would also be a big help. I am trying to model and draw these engines as accurately as possible.
Thanks.

Sincerely,
--Will
