The 1. cu. cross over, and the 2. cu. casts off · Then change places across : Then cast up in your own places, and back to back, then Right and Left and turn ·
The second timing symbol actually only has one dot on it rather than two, but looking at the print, the dot that's there seems to be where the top dot of a 2-dot symbol would be, not where the single dot of a 1-dot symbol should be. Given that the context is pretty clear that it should be a “ : ”, that's what I've put up there. The B is a single 8-bar phrase, hence the “ · ” at the end.
In the A1, remember the normal conventions in this period that a cross has an implied cast. Taken literally it's directing 1C to cross and cast, then 2C to cast straight back down again, leaving 2C proper and 1C improper. 1C then changes across back proper and we're all back where we started.
There’s a huge amount of time in the A2 to change places with your partner. I think there’s only one thing for it: foot it! It’s a three-time hornpipe, so rigadoon steps etc. don’t really apply – make something up, preferably ending in a 1-2-3 at the end.
Cast up in your places indicates not changing places with anyone. It could almost be a turn single, but since both couples have done a cross and cast already, it makes sense to wait until this point for both couples to cast back to where they started – which is quite nice.
For the rights and lefts at the end, 3 changes would be normal, but an extra cross-hand swing can be snuck in if desired, and that seems to be what they're encouraging with and turn.
To make it more equal, I quite like to have 2C cross and cast as well at the beginning; they can then join in with the cross over an foot it. It slightly tighter in the A1 but we have loads of time to spare in the A2. Typically you'd expect it to be for 1C, but 2C can join in if there's space.
