Hmmmm....I think I know that guy too! LOLThanks, Kirby. Hadn't seen that for a while. Looks like a very cool museum to visit, too. I just checked out their website here: http://fagenfighterswwiimuseum.org/index.html
There is also a nice promo video on the site. This is the youtube direct link: https://www.youtube.com/watch?v=n_2XBmsrWAo
On that video, there is a close up shot of part of their D-Day landing display, with a "soldier" manning a 1919A4. It's a dummy gun. How can I tell? Well, from the video you can't. I just happen to know a guy who built it for them...
