Yes indeed! Trunnion is more correct! don't forget, ALL projections/Fittings on the Sterling Receiver. Were electrically heated & brazed on in the factory. They were aligned on a jig to hold them correctly in place prior to 'fusing' on the receiver tube.
For the butt especially, it is CRITICAL to align the Trunnion properly. Or the Butt wont line up with the butt holding lugs recesses. On the inside of the Return spring end cap, When opened up!....

In NZ I think the repair bush on the butt was soft soldered in place in the reamed hole and then filed to thickness to eliminate side float. No need to weld, braze or hard solder because it ain't goin' nowhere!
We didn't use that method of repair but ploughed on with the ring punching method that solved the end float - temporarily. But still didn't solve the side float. Whereas the NZ Army method solved BOTH problems at once, permanently.

There’s a picture of a pivot/trunnion jig being used on the spot welder in Peter’s book (p144). That spot weld can make getting the pivot/trunnion off the tube quite difficult. The braze melts with no trouble, but that spot weld can be a problem.

Yes, that’s critical. What I found what works for me is clamping the butt in the end cap, with the cap pushed into the open position for the butt and the butt locking lugs aligned to just clear the recesses in the cap. Mind you, if you didn’t get the end cap locking ring aligned correctly on the receiver tube…
I wonder what happened to all the Sterling tooling, jigs, etc.

Roiyal Ordnance made sure that nobody could resurrect the Sterling gun from the embers of the old factory and tooling. It was crushed

The Sterling SMG is still manufactured under Licence. By Indian Ordnance Factories I believe?
Where they got their jigs from, or indeed. Manufactured them, themselves. I cannot say? More likely, the latter?......

Are they under license or did they just do it?

Kind of an odd agreement, no fees payable...
There must have been an up front payment and Sterling supplied tooling.
Having said that, the Indians (certainly at that point in time) paid no attention to intellectual property rights (FN-FAL / IA1, Browning Hi-Power / IA1, MAG58.... ect.)....
