Three speed box problem

[Charles P]

Sorted. There was a bit of play in the sliding bar, but mostly the gate change selector has too much play and after the lost motion is taken up the top gear dogs don’t engage as far as the detent. It works fine wit a ball change top. Actually I think I prefer it to the short lever.

Now then, the ball change I used comes off the Ulster and it wants it back.  I have a spare top but can anyone help me with a 3 speed ball change lever.

I have a whole ball change top, bit tired and needs the "ball change rebuild " process. It has been chopped down and adapted to Ulster size.
I'll conjure some photos
