There is a complete Universal Carrier 2 Pounder Equipped in the Canadian War Museum but it was not on display when I last visited. Theirs has a spare engine cover framework. I did take a lot of photos of the CWM one which I provided to Brook Quam in Abbotsford. He and his friends have another one and have mounted a 37mm Gun from a Staghound Armoured Car in a home-made mount and shield.
Here is my web page on UCs which I just started and includes photos of the UC 2 Pr Equipped - Historic photos, CWM's UC 2 Pr Equipped, and Brook Quam's UC 2Pr Equipped.
