More to the point, what happened to the tooling, does Dunlop manufacturing still exist in Aus? :shock:
There is a guy on the ad16 forum who has been researching for a couple of years the manufacturing process for these canisters. He was looking for a way to make them rebuildable. He was in communication with Moulton himself. In his research he found the tooling in England had been destroyed (for scrap metal?)
So there could be an opportunity if the Australian tooling has survived!

There was a group of us 1100 nuts trying to find the Hydrolastic tooling worldwide, we made a few discoveries but nothing solid. Then there was a bit of a split between the poms and the yanks in our group and the poms set up the ado16 forum, some of us have never spoken since.

I do know where the Hydro units were made in Sydney. I know the factory closed in the 70s and was converted into a shopping centre.
I never found where the tooling went.

I did find these on the net, from the State Library of NSW and titled "British Motors visitors from the United Kingdom inspect the Dunlop Rubber Works, Drummoyne"

The old Dunlop factory is now Birkenhead Point shopping centre.

Actually item 8 is, but it is only there to hold the piston in place :wink:

Sorry, my mistake :oops:
It does a little more than just hold the piston in place though.

Very nasty goodie :wink:

I do marvel as the resilience of the hydro bags even after 50 years they still
provide excellent service. Over built by todays standards.
If the idea was new today, they would attempt to make them out of fruit cans.
