RCA Varacoustic problem

I have a Varacoustic ribbon mic that I need some help on.The magnet has detached from the transformer,it seems they were just glued on from the factory.The transformer is mounted to the body,then there seems to be a gasket with a plate covering half the top of the transformer.The magnet seems to have been glued to the top of the plate with a brown glue.I need to reglue,but have no idea what to use.Does this stuff need to be something special? The magnet fits perfectly in the remains of the old glue.Need advice on how to procede.

Photos would be handy.

I often use Evostick rubbery glue for stuff like this, but you may prefer Araldite or superglue for stronger, but more brittle bonds.

I will get a photo up shortly.
