Which should you choose?
We will not advise between these two machines, because their unladen weight differs by more than 25% (48%); they were not built in overlapping years (1937–1942; 1947–1954). The figures below are side by side so you can judge them yourself; each says whether it was measured, claimed or declared by its source.
