Triumph Tiger 100 Episode: 2.04+
NYO 928, 1953 Triumph 500. Looks like an alloy head rather than cast iron so I think Tiger 100.
Triumph 6T Episode: 2.07
642 KMV, '57 Triumph 650, can't see enough to determine if T-Bird, Trophy or T110. Googling "triumph 642kmv" comes up with a few 650 Thunderbird references and possible pictures of a blue similar, but can't see a definite naming.
It has a headlamp nacelle which rules out TR6 Trophy, we have to call it something and my vote is 6T T-bird.
