Mike CT,
Your sweetheart did a fantastic job on that milk can. I love the bold colors and classic mill scene. And you have interesting stories. The farm I lived on briefly was a former veal farm, so it wasn't set up for milking. However, the farm dad also taught science at a local high school. He was great at solving various problems that came up, say, with the farm equipment or even my car. I learned things like "If a cause is unknown and can't be traced, replace the cheapest part first"; "9 times out of 10 that's all it takes". He was right and I've kept that lesson in mind when it comes to model trains.
Tom, thanks for the pix of the real thing. As a sometimes historian, I love the operations and other information that you can glean from the milk can tags; and thanks Scale City Designs for making the scale version. I'll need some when my boxcar comes in.
Great information everyone. And to think, milk is just one of the many items that had to be ready and in place for a dining car's daily run! (PRRMan, four volumes! Wow.) Now on to modeling operations for the proteins, fruits, and 
veggies! And, then there's all that table linen ...
