Frank,
The A7, the A/N 5854-1 and the A/N 5851-1(AKA Navy Mark V) allow use of the natural horizon.
The A7 is relatively uncommon but the other two turn up on e-bay from time to time, sometimes at silly starting prices.
The A7 is a handy little instrument, the A/N 5854-1 is prone to corrosion in the median device and the A/N 5851-1 seems to have been designed by a committee of deaf mutes.
