Sounds like a great buy so far. Congratulations.
Your statement "top lever right but action a bit loose" suggests that the top bolt which engages the dolls head is not worn, but the compensating screw in the front of the action knuckle may need to be turned inward a fraction of a turn. Weak, or even broken top lever springs are common in Lefevers too. If the action is tight when you hold the lever right, it may be a weak spring.
Keith,
There is a bit of play in the top lever. If I lay my right thumb against the right side of the toplever and put a slight pressure left, the barrels tighten right up and the toplever is still just right of center.
