I talked to your good people at the Classic Car Show (NEC) about an Alvis Speed 20 owned by my father.
I attach a couple of photos of the car, taken from an Isle of Man Tourist Board film made in the late 50’s or early 60’s. It had, I understand, raced on the Island before WWII – perhaps in the Mannin Beg race/s ? It carried the registration JMN 849. I would be very interested indeed to hear if you have any knowledge of the car.
Best regards Peter Standen
