Almost similar to First Edition (Falck Rykker Ud), but change in name due to the merger of Falck and Zone-Redningskorps in 1963, here the two companies worked under the unified name Falck-Zonen untill 1977 where the name changed again, this time to Falck.
The black ambulance on the box is registered in 1967. And the truck is too blurry to read the plate; It could seem that it starts with B; then it can be from 1970-73 - but I can not read if it is correct.
Black ambulance AJ 23.744. Truck UP 60. 60? from The station in Nørresundby.
