There are two here. One assembled. One pulled apart. Each strut can was loaded with oil and so were these tubes.

Maybe the pnuematic shocks from a 911E ?
http://www.caranddriver.com/comparisons/91...1e-coupe-page-4 QUOTE The hydropneumatic front suspension, made by BOGE, fits entirely within the MacPherson strut and is completely self-contained, requiring no external pumps or pressure tanks. And, since the entire suspension function is performed by a piston acting on a high pressure gas chamber, no springs or anti-sway bars are used. The car's height is controlled by the position of the piston in its cylinder. Regardless of the load, the piston can be moved to a predetermined point by adjusting the pressure in the chamber. For instance, when a load is placed in the trunk, the front of the car goes down. After you start to drive, an internal pump—activated by suspension motion—pumps gas from a reservoir to the piston chamber and returns the front of the car to its proper height. Obviously the bumpier the road, the sooner the suspension reaches the proper height—but only on a glassy smooth surface should it take more than a quarter of a mile. |

Very standard construction of early, pre-cartridge struts in many cars. When replacing, you toss it all and slide an insert in. I'm going to guess those are from a VERY early 911.

No, those are normal, non-gas strut parts. The hydropneumatic struts were far more complex, having a gas chamber as well.

When working on VW golfs years ago only found this once,undid the top nut and oil pissed out when I pulled the unit upwards,if I remember right you can't fit inserts in because internal diameter is wrong....sounds like the same issue.these were Boge struts.

Thanks guys! I wonder if they are worth anything. I am not going to use them. Maybe some CCW?

There is a good chance that they will accept inserts that fit Boge struts, as that is what they really are, even if they didn't come with cartridge inserts originally.

Arne I meant selling these inserts, not the struts. There are 2 seals for each, so they are rebuildable. Not much if any wear.

I doubt the inserts are worth any more than their scrap weight. It would take a truly rabid CW to care that a part no one can possibly see without significant disassembly isn't the same as original, even if just for bragging rights. Plus, modern strut cartridges are far better than the original equipment parts. |

My guess is hyrdro-pneumatic.
I always thought the hyrdo-pneumatic were unique and required complete replacement of the strut assembly, but I've never had my hands on them. Make sure you can use those with the front A arms. IIRC they don't all have compatible ball joints. |
