[Leica] IMG: Bench At San Pedro Valley State Park

[Jim Nichols]

Bob,

I've never used 645, but looked it up.  The actual image size is 
56x41.5, just a little larger than your 54x40, but quite similar, so I 
guess it was the closest existing size they could make reference to.  
Anything else that I could add would be pure speculation.  We never do 
that, do we? :-)
