Hello Peter,
I didn't put these pics on my website but here are a couple of the reversing gears in the gearbox – right hand side of photo:


This is part of the gear assembly that does the reversing – bottom right of the photo

I've got a CAD drawing of the gear assembly and bronze bush that I did for someone some time ago. Funny enough, they were missing the reverse gears as well. It's not the same lathe is it by any chance?
John
