Vespa VBB full resto:

[lambro]

Eek. Any of them?
Or just ones you've bought??

Ahem,
These Nam shites aren't mine

I do tell the owners of Nam junk what they have bought.
Only thing confused me was the fork tube, having been frantically looking at other Vespa frames in the last week or so, I have
found a VBA doesn't have one, nor a 152L2.
So I am now assuming that a VBB also doesn't, and the fork tube was introduced just after that era.
Odd though, 'cos it looks so wrong.
The steering lock is a bulky affair and is fitted from inside out, so with a tube in there it would be impossible to fit.

That said, it is still a horrible ghastly put together thing.

Im pretty sure the 152L2 hand fork tube, can't comment on the VBA though. As for the steering lock, it goes in first and then the forks, but if the bearing race is in the frame it can be very difficult. I feed a thin wire from the top and attach the wire to the lock and pull it up, it has to be in the locked position and once in place you must open the lock to allow the forks to pass the lock. This is the method I use on the GS.
