Raleigh Magnum cotterless bottom bracket assembly

[Dave Doust]

I have a Raleigh magnum with a TI Thompson bottom bracket assembly that has fallen apart.the chainset is standard square spline cotterless, but the majority of the axle is 17mm dia threaded with nuts/washers that hold the 46mm dia bearing race with 8mm bearings into the 58mm push fit cups
I am trying to find a complete assembly or everything except the axle.
Can anyone help me please?
