As I am doing my research, it looks like those are Flannery Bolt Co. barrel markings. It seems like they were a WW2 manufacturer.

I never saw that. The properties and colors of the two fabrics were noticeably different, especially after several washings. The OG507s didn't get starched.

Awesome! That would be Dulite-type Parkerizing?

Thanks very much.

Thanks Manny, I appreciate it!   Yeah, Alpine does really great figures and hopefully they'll come out with some in more dynamic poses.  Thanks again!   Joe

I believe it is intended as a joke, meaning when they dropped their bombs into the ocean they bombed a whale.

Looks like original finish.

The guidon. Upon re-measuring, it is actually 21 x 37 inches

I've checked on there different times and found some. They're always on there & probably is where I'll buy a couple. Strange how the Garand M5's and M16 M7's are so common, but I guess the M14 which took the M6 saw limited use year wise.   It's a great gun, but I also collect FN FAL stuff, which competed with the M14 in the 50's in US military trials for adoption as our main arm and came close, but politically it was a little too close to WW2 for relying on a European gun maker in Belgium.
