Do the AII-AIV series share the same barrel threads with the 75-85 series and or theL57/61’s

I'm amazed somone hasn't piped up about this by now, considering hundreds have looked at the thread. Would I be wrong in expecting the L61R and AIII to have the same thread?

I would just measure them; no one should be threading a barrel without having the action on hand.

Might be he's buying a used barrel to fit his action?
