Hello everyone, i am new here to the forum. My knowledge of millitary vehicles is linited at best, but am intrested in all vintage vehicles. My main interest is vintage tractors and these axles were used to convert tractors to 4wd with a few mods. How avalible are these axles in the uk and parts for them? I require a split type for a project and some parts for a banjo type for an on going one. Any help would be much appreciated.
