Hi. Ive just aquired a front axle that mainly appears to be off a series vehicle except it has 2 steel oval shaped pieces on top of the axles roughly where coil springs might be mounted on later landrovers, except they are not quite the right shape for take coil springs. It also has steel reinforcement running along its length which looks part of the original pattern. The number on the axle is 91116946 followed by a triangle. Any idea anyone?
