[Bruce Parker (RIP)]

I am looking for any information or photo's of the Bren 'Lakemann' mount as shown on this Covenanter tank. Does anybody know where there is an original? Any pictures that show what kind of clamps were used or how the Bren was secured at the front would be most appreciated. Are there any drawings in manuals for British vehicles, possibly Humber armoured cars? Anything in published material relating to Bren guns?

Thanks in advance.
