On the heals of last night’s post on the Nissan 4W60, we have the next major model of Nissan 4x4s which are sort of CJ-3Bish. They were produced from 1955 – 1960. You can learn about them here: 4W61, 4W65/ 4W66.
The 4W61 was produced from 1955 – 1958.
This is the 4W65 produced from 1958-1959. Now, while these have the correct side pieces, you can see the fenders look more like the 4W61. So, compare the front of the two below photos with the Black and white photo underneath.
The 4W66 was produced for six months in 1959 and 1960. I don’t have any good examples of this, but here’s a modified firetruck F4W66.
