The table is of various beer brewed in 1938 and 1939. Some were called as Pale Ale and some were called IPA. Can you tell which is which?
The IBU value is my calculation, based on the recipe. Got gospel, but at least a general indication of the bitterness level.
If you want to take part, just post a comment with your IPA selections.

I'm going to guess perceived bitterness was the driver here and say H is absolutely an IPA. G, J, M, and N are likely IPAs as well.
I may be a heathen,but how can an IPA be less than 5% ABV ?
E,J,Q ,R are my uninformed guesses as IPA's with the rest Pale Ales
Good quiz.
All of them. You have already made the case that there was no difference between pale ales and IPAs, just what the brewery wanted to call them.
After the War some of the weakest beers were labelled as IPA. For example Scottish and Newcastle Breweries IPA on draught was their lowest gravity beer and pretty much a "grandad's beer".
As for Greene King IPA, it's a run of the mill ordinary bitter at 3.6%.
Historically IPA was just about the weakest beer from a brewery. This continued after the weakening of beer during WW1.
If there is a pattern then the ones with the highest attenuation to be the IPA's?
So C E F H K O and R
I'll go for everything attenuated > 75% as IPA.
I agree in part with the first two comments.From what I've read from Ron on IPA, most beers labelled "IPA" at this time tended to have lower OGs, higher attenuation and higher BU numbers than "Pale Ales". However,Brits have never really been style Nazi's like we yanks. So C ,maybe H,K?,M and N?
A,B,L,M. I think I have seen something written about IPA’s from the mentioned period of time. Probably wrong.
D, E, F, I, O, P, R is my guess.

Well, Ron, how about ending our suspense?
