deniz ... all these were common British otc blends. Some (eg Clan and Gold Block) were fine ribbon cuts .. but others (eg Condor and St Bruno) were less so. You could buy flake tobaccos but they tended not to be advertised on TV. Re the 'Scoop' - there is the 'old codger scoop' whereby experienced smokers could fill their pipe like that. I fact, I do myself if I am filling it on the move. However, in the ads I expect that they use the scoop to avoid spending more than a second or two on that shot.

PS Mellow Virginia isn't a bad tobacco at all. Here's my fave MV ad, not in the above group: https://www.youtube.com/watch?v=P96wWx_fVyQ
