Hmmm---I think it is actually a MG-42. The 34 didn't have those oval
holes in the barrel shroud.
It doesn't have a barrel installed in the picture, but for those that don't know,
the barrel on a MG-42 (or 34) can be changed in seconds. REALLY neat
feature on a aircooled beltfed, especially one with the cyclic rate of the 42.
Scroll down a bit, there is a pic of the barrel swung out for changing. Flip[
it out to the right, jerk the old one out, slam a new one in, latch it back
