Er, yes and no. The ingredients are the same: mild malt, crystal malt, No. 3 invert sugar, Laevuline and Sucramel. As before, I’ve substituted No. 2 invert sugar for the latter two proprietary sugars. Though the ingredients are the same, their proportions have changed again. There’s more sugar and less malt this time.
The big change, however, is in the hopping. The quantity of hops has been halved, reducing the IBUs from 31 to just 15. It would be interesting to look at the intervening years to see if the drop happened all at once or gradually. Clearly it would have left the beer tasting very different.
The OG has returned to 1075º, up 2 points from 1977. But the FG is a lot higher, causing the ABV to fall. I imagine that the real FG would have been lower as presumably it received some sort of secondary conditioning.

How much Laevuline was in these recipes?
I wonder whether it is L-glucose, which tastes sweet but cannot be metabolized, used as an unfermentable sweetener, a bit like lactose.
L-glucose is very expensive compared to other sugars, since it has to be synthesized. So probably not.
This source ( https://play.google.com/store/books/details?id=ipgvAAAAYAAJ&rdid=book-ipgvAAAAYAAJ&rdot=1 ) mentions laevuline - it appears to be invert syrup.
Regarding something I asked about past sugar posts, this looks like a good writeup you did a while back:

Googling around a bit, it looks like Laevuline might be a reference to Levulinic acid -- it appears to be produced when heating sugar with acid, which is part of the process of creating brewers invert syrup.
