Getting parts for your pre-war beloved one is one of the hard aspects of the hobby. No wonder PreWarCar's parts section works so well. The marque specialists work very hard to have reproduced important no longer available bits. One of the forerunners in this area is Ecurie Bertelli who is offering a massive choice of parts to keep on the road the mere 450 or so Aston Martins produced before 1940... Quite handy when you need new kingpins for your LeMans as pictured above. Check their new website, go to their parts section and use the searchbox to see what's in stock. Type Manifold or Clutch. Just give it a try with the parts that come to your mind.
Now when you have 'larger' needs (like one on four wheels) it may be good to know that not all cars which are available at Ecurie Bertelli are visible on his website. Just contact Andy Bell and he can tell you more about an ultra rare Ulster that will come in soon and possibly a short chassis LeMans. Whatever the conditon these cars are in before a full Andy Bell treatment, it's a reassuring thought that worn out or missing parts probably won't be the problem.
