Does anyone know what’s wrong with these Geiger counters?

The Grey one’s needle moves a bit and only one light seems to work properly while the Bakelite coloured one has both lights working nicely but the needle doesn’t move at all. Both needles do wobble right to left if I move the device itself but other than that they just do what I said before.
