87 is probably correct, I didn't notice that and was concentrating on the painted numbers. Airfix has been around a long time but they are tiny about 3/4 of an inch tall. These are two inches tall so more detail is present.
I have a lot of Airfix and probably half a dozen other manufacturers, but most are Napoleonic era. I do have some WWII but they are just what I picked up incidentally. I always say I'm going to sit down and paint them but haven't done so in a long time. I have thousands of them so maybe when I retire.
