Road goods vehicles in Ireland 1950s/1960s

I’m wondering about a couple of lorries for my layout, as there are road loading bays as well as rail. 
In the 1950s/1960s, which marques would have been seen in south-west Ireland? I think I’ve read somewhere that there were tariffs on imported complete vehicles and so some firms did final assembly in Ireland, so those would be more common. 

Looking at a few CIE vehicles of the period, a lot of them seem to be AEC, and later Leyland, badged.

But there are also some Fords, not obviously CIE in this case:

For this sort of size truck, is my choice basically AEC / Leyland or Ford? And were there particular models more common in Ireland? What other options would there be?

I think in the 1940s, GSR/CIE had a dominant position in the road transport business and the role of independent firms was quite limited. I expect that had changed a bit by 1960. Would independent hauliers and/or industries have been more significant than CIE by this time, or was CIE still dominant?
