I did a google on besa for you and got this Not what you are looking for I imagine but I thought you might be interested FNG[/img]
There's one on my site, in an article about the .5 inch Vickers - see below. It's the Czech original, on a spring-wheel carriage. Tony Williams: Military gun and ammunition website and discussion forum
i know the 7.92 besa was used in tanks but i thought the 15mm was only used in armoured cars such as the humber
It was also used in the Mk VIc light tank - this had coaxial 7.9mm and 15mm Besas, whereas the Mk VIb had Vickers .303" and .5". TW
