Hi there, In my garage I have a none working floor standing hydrolastic pump. It was built by Stirling hydraulics millions of years ago. The badge engineered Cope, is very similar. I bought it unseen, Stripped it, replaced many parts but in the end failed due to stripped threads in the change over valve, and the pump side did work and the vacuum side did but not very well. I've stripped and repainted the main tank inside and out with Hammerite and fitted a new fluid level sight tube on the side. It's all there but in bits. I've now got a new pump now so gave up with this one. It comes with working pressure gauge and a brand new vaccum gauge still boxed. All its hoses and flexible pipes and some new pipe and fittings. The brass pump is all there too. So is the original proper Schrader low loss connector. The original operating instruction plate it here too.
So, if you have a Stirling/cope pump there are some very useful parts and tank here for you. The tank is water tight and looks good.
I'm not looking for big bucks or anything like but a few quid or a swap for landcrab parts like a nice MK1 steering wheel or something like service bits. I dont want to scrap it because I'm sure somebody out there will want it for parts. Shout if interested. .
