Harley-Davidson FL Episode: 1.10
Harley Davidson FL as built until 1971 because it has a drum front brake, but I can't see if it has a panhead or shovelhead engine to determine if it is a Duo Glide or a Electra Glide

The paintwork isn't quite right but I reckon Z1A with period Lester mag wheels fitted.

Triumph unknown Episode: 3.10
I think it's a Triumph, too blurred to tell if it's a T120 or T140 Bonneville.
It has the conical front brake hub which limits the years down to 1971 or 1972, probably, even though I think the hub might still have been available for a few years after.
