Grimp's Fotothing

Some more from the old negatives box.
These must have been taken in the early 1950s on Luxembourg airport.
Can somebody identify the carrier. I think the plane is a DC-4.

These five negatives were in quite a poor state most certainly due to poor washing and remaining chemicals on the film.
