Fantastic. I've seen it before, and it's great. Some random thoughts:
Usually, when it comes to '40s cartoons, I'm a Warner Brothers man. However, Disney did well with this one.
Rarely are hardcore technical info about firearms and family-friendly animated entertainment found in the same place.
My interest in modern .50BMG rifles (relatively low, no offense to .50BMG aficionados) is almost wholly dependent on their resemblance to crazy WWII anti-tank rifles (Boys, PTRS, etc.)
The phrase "Boys rifle" will connote to many a single-shot .22lr. To others it will denote something quite different, illustrated most excellently in these clips. I think many of the readers of this forum fall into the latter group.
British guns are weird. Magazine on the top, offset sights (a necessity due to the former), backwards pistol grip.
Pretty obsolete concept by mid-war (anti-tank rifles generally, not just the Boys), at least in respect to frontline tanks. But the idea of the anti-materiel rifle survives.
Okay, that's enough. Thanks for posting this!
