One moment please…. We are experiencing technical difficulty….

As a Dakkite pointed out, I had the legs on the cannon backwards. I was thinking about the old wheeled gun carriage when I put the single leg to the rear. These are aimed turned by turning the complete carriage.

As this is a pintle mount it would have fallen over when shot with this configuration  :- P It’s always good to have another set of eyes on these things…

Here you can see the revised model and gunner position.
