Dwight,
I have another movie to add to the list:
"China Girl"
Released in 1942, Gene Tierney, George Montgomey, Victor McLaglen (of John Wayne western movie fame as "Sgt Quincannon")
Multiple great clear shots of Lugers and holsters on a couple of the AVG fliers, and also by the main character and several others in the movie....
Didn't get to see the whole movie but based on spies in China during japanese invasion and the flyboys of the AVG with a white female and male being jap spies on the AVG activities.
In one clear example, the main character "Johnny" played by George Montgomery asks to borrow the sidearm of his AVG buddy and he opens up a luger holster on his right hip and hands him the luger inside, he then uses it to threaten the jap spies at the breakfast table.......played by Lyn Bari ("Capt. Fifi") and McLaglen ("Major Weed")
Watched it partially on either AMC or TCM today..........
Interesting side note: the little chinese boy helping "Johnny" in the movie is no other than "Robert Blake" that was accused of killing his wife or whatever she was with a WWII P38.........
