Can you imagine the outrage and outcry today if a person was told to test the Non Return Valve (NRV) by blowing cigarette smoke through it, there would be a #hashtag movement started in minutes and questions raised in the Houses of Parliament or Government, KZitem would have thousands of new health videos uploaded and social media would crash from the amount of traffic that suddenly started. Thanks for sharing this interesting and informative training film, a good look back into history and the norms that were part of the era. 👍

Dj Phantom We put our nasty mouths on the check valves to test them. One person after another. Hopefully no one’s a germaphobe.

I did an apprenticeship 1978 with 2 retired Senior Chiefs when I was going thru a program. Both of those guys smoked camels since like the early 50s,. Our locker had 2-MKV's, a couple of Jack Browne rigs and KMB10s, the MK V's smelled like shit but I didnt care I was the happiest 18YO kid alive. At the end of every evolution id have to polish that Mk V ( "Elbow grease son elbow grease") While the rest of the guys would be drinking PBR on the tailgates of the trucks. I wouldnt change a thing...
