Rear wheel spindle problem?

[Sun Superlight]

My back axle has just broken and I need to find a replacement.
The hub is a older six speed freewheel type and has shielded ballbearings rather than the usual cup, cone and ball'stype of arrangement.
The axle is a solid one. It's length it is 170mm with a turned or ground unthreaded centre section to seat the 10mm bore of the bearings.
The ends are threaded M10 by 1mm pitch which I think is a standard size.

It,s still a fairly standard axle, it should be available in most bike shops. Good luck with your search.
