As Col. Potter finishes his toast to his fallen friends, a close-up of Charles and Klinger shows Charles holding his glass of brandy in the palm of his hand with his fingers pointing upward to hold it. In the following shot, Charles is holding his glass from the side with his fingers wrapped around it.
Potter goes off on a rant about people having to eat horses, but in earlier episodes, he mentions having to eat horse meat during WWI and it didn't bother him at all.
When Col. Potter mentions that the brandy had been very smooth in 1917, Winchester remarks that "it should be magnificent now." Distilled spirits only age and mature when they are in the barrel. As long as they are stored properly and remain sealed, once bottled they do not change to any significant degree. Potter's bottle, assuming it remained sealed, would have been much the same in 1952 as it had been in 1917. As a wine and spirit connoisseur, Winchester would know this.
When the gang clinks glasses after Potter's toast, Charles misses all of the glasses and doesn't clink anyone.

In the mess prior to Potter's return, Halpern gets one of the children to eat some eggs.
The child makes a face before the food touches his lips.
Later, after Potter leaves, the same child is seen happily eating food.
