HO scale 2-10-2 information needed

[NW Modeling List]

I have access to both a Spectrum and IHC 2-10-2 (and a Proto 2000 as well), 
and should be able to take a look at them Friday or Saturday.  I do have one 
question: How do I determine the throw of the crank pin?  I model steam, but 
will admit to being a layman with regards to some of the terminology.  The 
driver diamater, powered axle, and driver spokes should be no problem.  Do 
you prefer an answer through this list, or direct to your email address?
