I’ve had Mills Fuel on my layout for several years, but it existed only as a sign by the siding.
I could not decide on what the office building should look like.
Then, inspiration struck. It should have been obvious all along.
Mills Fuel is named after Fred Mills, from Ottawa in Canada. Fred hosts operations sessions every week at his house, and also hosts the American Invasion each July.
His workshop (pictured on the right) would be the model for the office of Mills Fuel on my layout.
