Australian LP2 and LP2a small parts
 

here are some of the small parts used firstly to locate parts (bushings) in the suspension castings, and secondly the 3 types of breathers used.
The short square ended breather has no valve and is just open to air.
The long square ended one contains a spring and ball, and so would hold a little pressure.
the third one with the spring loaded externally seen valve, is a universal one still used today.
The zinc wash is not original. I had that done.
There are some original bif rivets shown as well.
I would be interested to know the useage. (if one replaced the other, or if different producers used the different types) ( I dont have a parts book)
