Now you are getting complicated. The system was changed in 1956. But your question concerns a 1955, so let’s stick with the question at hand.

1. Yes it is as expected.

2. Touching your meter to the switch terminal, it will show continuity to ground, via the closed points and/or coil primary, as previously discussed. But, AHA! The switch housing is also grounded through it’s mounting bolt. Therefor you have continuity as discussed and also to the switch housing, because the switch housing and ground are the same thing.
