I would be sticking any bag in there. Just like the last bloke did. (I already pointed out that the current bag is the wrong one for that car.)

As it's an Australian made bag, if you power wire brush the outside, you should find a part number on there.
These days, any bag that doesn't leak is a good one. It's hard to pick and choose when exact replacements are unobtainium.

Exactly what bag are you after? 

Thanks...I spoke to Jack about that one...wrong year....Still need help!!!!  This is like the search for the holy grail.....I have some nice original S parts I'll trade????  Maybe that will bring out someone hiding in the woodworks???

Thanks!!!

 

Wow this is getting a bit depressing....There has to be someone on this planet with a spare hydro bag that will work....Help!!!!!!

In recent times due to scarcity of S bags, some Cooper S cars here in Oz had to get stock Mini Deluxe etc bags fitted instead. They work OK, but you would need a pair as their spring rate is different.
And, it's preferable then to swap the stock S rear bags to front and put the commoners in back. This is the setup in my car for the last 20 years, it sits level, rides and handles well.

[edit] These bags are all 40-50 years old now. I'd take a good hard look at the hoses and their crimps before fitting to car. Replace hoses if in any doubt.

Thanks for the input....at this point I guess beggers can't be choosey...as long as it is the correct fit and its in excellent condition, I'm not sure I care if it says UK or Oz, etc....This is a bit of a learn as you goo process so any constructive input is appreciated!!

Thanks!!

I don't think the Australian Cooper S got locally made displacers till late 1967. (from car #3717) 

Mark thanks for your offer....the hose is dead nut perfect....The bottom of the bag has a small tear in it....bummer....

I was able to repair a bag. My leak was in the hose. I find it hard to believe that the bag is damaged inside the metal housing. I'd be happy to repair it if you want me to look at it. I put together a pretty bulletproof system.

Australian variant.....

Why would a 65 Cooper S have an Australian bag? It must have been swapped previously.

Hydro bag pulled and the top says made by Dunlap Australia under muoton....The unit is black with no color markings....Let me know if anyone can help me fing a replacement....

Thanks!!

 

I would try Paul or Alex of Minimal Motoring. There was a gentleman selling off parts in the back of his truck at MME this year. He had a set of four that laid around unsold all weekend. I know Paul was interested in them, he may have eventually ended up with them, or know who got them.

We were not sure what car they were from though, they could have been 65 S.

If you are a member of the mk1-forum there has been a large topic on Identifying Hydro Units.

whee & Werewolf thanks for your help....I know its hard to part with these so unfortuanately I realize I will need to be patient...I hope to have the original out tomorrow so I can determine the markings....if you have a contact for deb that would be great....

 

Best!

 I think deb franks has some spare hydro bags.. in NY.. you might call her.. 

If you are totally stuck, I have a couple of spares. I don't really want to sell, but I could do a "lend" to get you back on the road.

Email me if this helps. (am on road - so will be slow to reply)

Any help or thoughts where to search...Thanks a bunch!!!

Thanks a bunch Jemal!  Good chance we know each other...

I forwarded your post to a friend in also in Arizona whom I know to have about 8 of the bags from his 2 Cooper S cars.  I see you have contact info... maybe he'll contact you.
