the same thing happened to me Bilko,
I was driving to Brussels on the E40 at about 65mph and sensed an odd vibration coming on,
When I got to Brussels I noticed nothing special when I checked the bike.
When leaving from there the layshaft snapped and rear hub just blocked under the mudguard.

The original innocenti layshaft was torn all through just behind the nut,
the nut, the safety plate and little bolt were still there.

We were lucky it happened in a street instead of the motorway as we were driving two up...

iv"e got two locking plates on mine, and a longer allen bolt. been on for years .

MB make a thicker locking ring in stainless

it is thicker than normal so it does not loosen under the standard Lambretta rear hub nut.

I've just fitted one and the picture doesn't do it justice as it's about 5 mm thick, much thicker than the one I had on before.

I have had one go as well. Doing a run form Richmond to Pittsburg through the mountians of West Va., two up. Just got off a mountian freeway raod, blatting along about 70. Get off the freeway, pull into a small town, stop at stop sign. go to pull off and thud clunk, wheel under rear fender. Not a good feeling. Good job there was a pub open just down the roads for some nerve juice. I put it down to a bad Spanish axle.

this isn't turning into a metal fatigue type problem is it?

After all these bikes/ axels are now around 50 years old, and have experienced God knows how many tightenings over those years- they surely weren't designed for this lifespan were they?

I have to agree with Bristolmods post on this,and dont forget that they are now used on generally more powerfull motors than the 10bhp ones that they were intended for and coupled with the fact that most folk yuck these up to the max when putting the nut on anyway.

That's what goes through my mind every time I crank it up to 120 lbs then god only knows how many extra lbs getting the washer to line up.
