Race Cars and Motorsports

The latest addition to the BritishRaceCar gallery is:
Syd Silverman's Costin-bodied Lister Jaguar Race Car (write-up plus 48 images)

Can you help me improve this article? As you look through it, you'll realize that the car has changed a lot from what it looked like in 1959. Over a dozen owners and about a dozen restorations... So, some of what I've been told about the car doesn't match what I see in the photos. Maybe you can help me identify:

1) who made these front brake calipers? (They don't look like Girlings to me. AP?)


2) what donor car provided the front suspension uprights? (Morris Oxford would be original, but...)


3) what's this yellowed plastic reservoir for, rearward of the headers? (It ain't for windshield washer fluid!)


(The lid looks like the Lockheed master cylinder lid on my MGB... but smaller.
However all three master cylinders are located on the opposite side of the car.)
