No doubt the Trado inspired the Engesa engineers; could well have been they outright copied it, though.
The Scammell must have been around before the Trado (introduced in 1934), so most likely Mr Van Doorne en Mr Van der Trappen found some inspiration there. The real differentiator was the fact that the Trado was a conversion kit, while the Scammell walking-beam was an integral part of the truck.

After the war Spanish military truck series were patterned on the contemporary DAF series.
Weren't those license-built DAF's?
