Re: VERITAS AEQUITAS!
They had peaked lapels, so "ordinary Naval Peacoats" wouldn't be accurate. Unless you found one with peaked lapels, and most were made with notched lapels.
I know I'm raising the dead here, but the coats worn in the movie /did not/ have peaked lapels.
For the first 3/4 of the film, the brothers are wearing Navy-issue Sterlingwear peacoats. The manufacturer is evidenced by a particular style of stiching at the bottom of the coat (this can clearly be seen as Connor is walking toward the camera -- toward the payphone -- in the police station, about to dial the number on the pager). This also makes sense, as Sterlingwear's full company name is Sterlingwear of Boston.
Plus, I was in the Navy, and was issued a Sterlingwear peacoat. They're hard to miss -- I can spot one right away.
Beginning when Rocco drops them off for morning Church services, just before Smecker exits the bar, they are wearing much older coats. Look closely at the close-up shot of Connor's hand holding Smecker's business card. There is clearly a single line of stitching about 2.5/3 inches above the cuff. That indicates a post-war coat, ca. late forties, /possibly/ early fifties according to my notes. Either way, it would've been made by the Naval Clothing Factory. Then, during the courtroom scene, examine Murphy's cuffs as he is holding both guns out, speaking to the crowd. There is a visible double line of stitching (3/4 inch apart, about 3 inches from the cuff) on his sleeves. That could be a fifties coat all the way up to 1967 -- 1967 being the last year any sort of stitching was placed on the cuffs, save for the single line 3/4 of an inch above the cuff on Vi-Mil (first manufacturer of the Melton-wool coats) and Sterlingwear coats. So Murphy's coat in that scene was made by either the Naval Clothing Factory, or by Kersey.
NONE of the above manufacturers, including Sterlingwear, have ever made peacoats with peaked lapels -- peaked lapels are not per U.S. Government standards.
Just wanted to clear that up.
