Unlike in England, Porter was brewed right through WW II in Ireland. Its popularity, however, did seem to be on the wane. The amount produced may have increased a little, as a percentage of Guinness’s production, though, fell from 36% to 25%.

Sadly, I’ve no intimate details of Guinness Porter. I do, though, of another Irish Porter, that from Perry.

This version has a gravity similar to pre-war Guinness Porter. Except with a shit degree of attenuation. I’m not convinced that those FGs are the real ones

Compared to the pre-war version, the hopping rate is a good bit lower. In the case of the 1943 beer, not much more than half that of 1935. I’m guessing that this is connected with the interruption of hop imports and the limited amounts of English hops available.
