Hi Tony

I agree that a trunnion method similar to what you have drawn could be a good answer to the problem. It's very similar to what I'd imagined the fitting would look like.

The square hole does suggest that it's for stopping rotation but the springs aren't a counterbalance, they're far too strong. Even with the leverage of the gun you'd have to really force against the springs for any sort of evlevation, you can't compress them with your hand.

There are pictures of Scouts in a line and the gun barrels are all at the same angle and another at different angles, this suggests that they're free to move. The part at the rear of the flat rotation plate is a rubber rest. I've assumed that the gun sits against this when not in use, when needed the gunner lifts the butt and has free movement in a similar fashion to the way the Bren mount is used.

I've looked at an unhealthy number of period carrier pictures to try and understand how the gun fits into the mount, no real answers. Discussion here is good as it gets us all thinking.

Thanks

Ben
