Are there any perm magnet in it?
If not, then there might be two coils: one is creating magnetic field and one is the small moving coil attached to the needle. Same principle as in the speaker with field coil.
If this is the case, then you should have two wires with continuity and two other wires also with continuity, with no continuity in between the two pairs.
If this is the case, then I would guess that the larger resistance is the field coil (probably is fed with a DC voltage) and the smaller one is the output (goes to the amp's input).
Now this said, I have no idea what I am talking about so treat it as such.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
