My Pattern 12 front axle has the Bendix style joints both are in very good conditions.

As to the felt wipper and springs in the front ball seals my HUP had what appeared to leather instead of felt so I got some leather belting and cut strips the right size off. I used the same stuff on the C60 Pattern 13. Have not decided what I'm going to do on the Pattern 12. I took the felt seals out very carefully and they are not in bad condition. I may clean them carefully and put them back in.
