Can you name these Dublin locations 1-3?

Dublin locations in The Big Gamble (a 1961 movie which tells the story of a Dublin sailor who goes to Africa). Pics not great but screen grabs are limited to the few minutes that are on Youtube.

My initial brief attempt to identify location suggests somewhere around Old Kilmainham but Dubliners please feel free to correct me…

Anyone?

Also: name those jammers, anyone?

The Big Gamble (1961)
