Looking through photos of "saloon car" racers from 50 years ago I found such an interesting fact and I would really like to know how it happened. Namely, on the legendary MGC GTS "Mabel", which in the hands of Hopkirk and Hedges won 10th place in Sebring 1968, there are simultaneously (yes, on the same fender, a few inches apart) Castrol and Shell stickers. We all know how fiercely these companies competed with each other, hence my question: who provided oil for the BLMC team in this race - Castrol or Shell? And how on earth is there a competitor's logo next to this supplier?
What's even better, the same situation appears on the Escorts Mk.2 RS1800 of the Zakspeed team in 1976. Both the Finotto/Mueller car, starting in the ETCC as #27, and the car of Armin Hahne (#33 in the DRM series) also have Castrol and Shell logos next to each other. Does anyone know the circumstances of this conjunction?
Cheers
Michael
