Cutaway! 1957 Triumph Training Aid

Disclosure: This site may receive compensation from some link clicks and purchases.

All of you have seen cutaway drawings; those detailed artworks where parts of a car appear transparent so the inner workings can be seen. Here’s a chance to own the real thing; a Triumph TR3 chassis and drive train that have been sectioned in various places so that observers can actually see how the car works! Not only that, but it’s the star of an educational presentation on how cars work! It’s listed for sale here on eBay and is located in Arlington, Texas.

Only close ups of the chassis are posted in the ad, but here you can see inside the engine, how the distributor is driven as well as the innards of the coil and fuel pump. All the parts are genuine and after reading this behind the scenes article it appears mostly scrap parts were used when the chassis was put together , so if you’re wondering about someone doing this to a perfectly good car you can stop worrying.

I know the innards of TR transmissions a little more than I’d like to. I wish I had learned from observing this unique training aid instead of having to rebuild one so I could get back to class on Monday!

I’ll bet many of you don’t even know what a lever shock absorber is, let alone how they work. I hope all the organic-based fluid is long cleaned out — there is no smell on this earth like original British organic shock fluid after it’s been cooped up for 40 years–and I don’t mean that in a good way!

Ever wonder how an SU carburetor works? Here’s your chance not only to learn but to show others! I hope this dramatic cutaway finds a good home and is used to educate future car folks on how these charming British cars work! Do you have a home for this unique cutaway?

Auctions Ending Soon

    Probably doesn’t leak any worse than a non-cutaway model. LOL

    I don’t know if there is a museum for British sports cars, but if so, they are going to want this. Wait a minute- gone!

      Hi, Fred — I’m not sure why the auction was ended early. Hopefully it will come up again.

    The British sports car parts retailer I used to work for sold really nice reproduction “glass bowl” fuel pumps for the early TRs. It’s a design that’s both primitive and complex somehow, and I always thought they were wonderful to look at.

      The AC fuel pump glass bowl on my former ’54 Chevy truck also fit my TR4.

    It looks like it’s meant to show all the parts that are going to fail.
