Gentlemen
I was a final year apprentice toolmaker at the gun factory in 78 and I machined a drop stamp die," - on the roundabout" for the new pattern wheels - 6 stud, to supersede the 101 Land rover wheels 5 stud, that were used originally. They stopped making military pattern 101 forward control land rovers in that year and I assume wheel matching was no longer relevant.
Kind regards
Ian
