OK - I skipped a few. But I have just been told that my son has his video on YouTube. I searched using a variety of possible tags - and finally found a lot of videos about 'beretta' (he's just joined a pistol club). Scrolling through I spotted a familiar looking silhouette. Sure enough, it was Mark rapid firing the beretta.
So, following Helen's Blowers' instructions I have uploaded the video for all to see.
