Read my old article “Dunlop suspensions” where I tried many times to get Mr Moulton to help us with drawings or how to get them made. He said it was impossible to resurrect the part again even though I had a wealthy customer willing to pay for new tooling, but on enquiring with Dunlop all the old tooling had been scrapped and found that they had been loosing money on rejections when testing new units, so I reluctantly gave up any serious further investigations.
