The DC-4/C-54 with the red stripe is probably this one
www.spiritoffreedom.org/. The other one painted in MATS colours is on the airshow circuit in the US. I can't remember who owns it. There are several DC-4's still working for a living in this country, with Buffalo Airways. Sadly, one of them was damaged, probably beyond repair, in a landing accident a couple of weeks ago.
Go to
www.buffaloairways.com/ and click on heavy freight or fire suppression to see the '4s.
A quick comment. If a DC-4 isn't history or nostalgia, I don't know what is.
