Any ideas about this?

This is the layout of the universal joint that connects the fuel control shaft to the three-way Main Fuel c*ck on the Hawker Typhoon. We are at present doing a restoration to static on this component, but only the two fork ends are present. Is the internal connection of the joint a simple ball bearing… or something a little more complicated? There are no drillings for any internal interconnecting spigots in either fork end; merely bolt holes for connecting the fuel c*ck spindle and actuating shaft
The operating body of the joint is shrouded by a rubber boot (We have salvaged the original.) If it is a simple ball bearing; how the heck did they manage to insert it into the centre of the joint? The gap across the tops of the fork horns in each fork end is less than the circular space between them.
The location of the U Joint is circled below:

Any clues would be much appreciated.

Thanks gents;
That confirms what I thought.

Can’t find any bits at the moment. The ball was not a simple ball bearing. It had grooves at 90° with flats in them. One fork had a ground “track” in it for about 3/4 of its end. The other fork was similar but with a gap in the “track” to facilitate assembly. The ball and forks were “hardened” and had to be lapped together to get the correct movement and fit. A pin was then fitted in the track gap to prevent it coming apart. I hope this makes sense, it was about 15 years or more ago that I last worked on them.

You mean one of these?[ATTACH=CONFIG]232037[/ATTACH]
This one is for Westland Wessex helicopter fuel c0ck.
**** I’ve just said **** again.

I used to make these joints when I worked for Mollart Universal Joints. The aircraft division was sold to Davall Gears at Hatfield. Could try there, or I might even have a few odd bits lying around in toolboxes
