Ok you guys and girls, a little poser for you.

I was chatting to a client this morning about Roger Marshall.
Eventually we started to discuss "V 4 Victory", and whether Roger rode the V4s in the TT. I didn't think he had at first, but then it was pointed out to me that Roger was runner up to Joey in the 1984 Formula One race. Thus, surely he rode a V4 750 that day?
Although I was riding the TT in 1984, I didn't have an F1 bike, and just cannot remember the race.
I think that Roger rode a VF1000R in the Production race. Does that ring any bells?
