The axle housing looks just like my Schindler, even the knuckles look the same. Generally, I need to look at the axle end at the lugs. Schindler's are flat, have nothing sticking out of the rim, whereas the other conversions have bolts and protruding axle stems outside the lug nuts and rim.
Its the ujoint couplers that threw me. My Schindler uses a metric bolting u-joint spider on each side, that bolt to inner and outer axles.
Those Britians on the World Forum have them ID'd by photo, various times.
