Needed: Diagram of Valve Gear with dimensions of components

Looking for a picture of any US locomotive with Walshaert(s) showing the dimensions of the components, e.g., length of rods, angle of eccentric, etc.

Anybody know where I can find such a diagram or blueprint. If it happens to be a "high-interest" locomotive such as a NYC Hudson or PRR K4 or any anthracite road engine great, if not that'll be fine as well.

Super,
would this work?

this is Bridgton & Harrison #7,
a "Maine 2-footer" built by Baldwin in 1913.
she still survives at the Maine Narrow Gauge museum in Portland ME.
this doesent show the actual dimensions of the gear, but you could extrapolate it from the other dimensions given..

I have a valve gear print of a Pennsy E2d specifically listed as Walshaert. I also have a valve gear print of a K4 with no Walshaert notation. Both contain dimensions. Let me know if you would like me to send you copies of either, both, none.

There is a book " 100 Years of Steam Locomotives " edited by Walter A. Lucas published by Simmons- Boardman Books probably out of print That has pictures & drawings with dimensions of literaly hundreds of locomotives. Very interesting book.................................................Wooly
