Some more photos of the truck.  It will be for a passenger car.

Jim built the window frame.  He had a local jeweler make the window itself.

Post Script  I'm trying to get rid of the distortions.

And I thought I was jumping into the deep end with a switch from HO to Proto48.  Really beautiful workmanship!

Very nice, thanks for posting.  Since this scale isn't very common, I'll explain before someone asks...

The proportion of 1/20.3 is what is known as F scale.  It starts with 45 millimeter gauge "G scale" track as representing 3-foot (narrow) gauge.  That is, if you multiply 45 millimeters by 20.32, you get 36 inches.  So, this would be "Fn3".  Carrying that over to standard gauge modeling, track gauge then becomes 2.781 inches, or 70.64 millimeters (56-1/2 inches divided by 20.32).  Obviously, a fair amount out there available for "Fn3" (Properly proportioned G scale equipment and its track), but standard gauge to match requires nearly all scratch building.  There are a few products available from small manufacturers.

Edit:  One last point of reference - In terms of "fraction of an inch to the foot" scale, F comes in at just a little larger than 9/16" equaling one foot.

Thanks Mark 

You typed everything that I was too lazy to do, and then some.  I tried to answer some of those questions when I placed that dollar bill next to the truck.  When trimmed properly at the Mint, a dollar bill is six inches long.

That is a true work of art.
Curious, how many hours went in to building this treasure? Amazing workmanship.

Thanks, Jack

It is actually easier to scratch build in that scale and make it function. Everything being larger.
